+# The only purpose of this rule is to pass Mozilla's Tinderbox depend
+# builds (http://tinderbox.mozilla.org/showbuilds.cgi).  Mozilla's
+# Tinderbox builds NSPR continuously as part of the Mozilla client.
+# Because NSPR's make depend is not implemented, whenever we change
+# an NSPR header file, the depend build does not recompile the NSPR
+# files that depend on the header.
+#
+# This rule makes all the objects depend on a dummy header file.
+# Touch this dummy header file to force the depend build to recompile
+# everything.
+#
+# This rule should be removed when make depend is implemented.

+**
+** If there is not enough space in the arena pool->current, try

+** freelist (arena_freelist).
+** 
+** If no arena in arena_freelist is suitable, then try to
+** allocate a new arena from the heap.
+**
+** Returns: pointer to allocated space or NULL
+** 
+** Notes: The original implementation had some difficult to
+** solve bugs; the code was difficult to read. Sometimes it's
+** just easier to rewrite it. I did that. larryh.

+NSPR 2.0 libc functions
+-----------------------
+
+Last edited: AOF 04 March 1997
+
+This directory contains various libc-types of functions. All functions in
+this directory are platform independent, thread friendly (both safe and
+efficient). They are contributed from various sources, though the contri-
+butions are monitored by the NSPR group (mailto:freier).
+
+All API items exported by these functions will contain the same three
+character prefix, "PL_" (Portable Library). Internal function names
+that are not exported (static) are of little concern, though some caution
+must be used on those elements that are 'extern' but not really intended
+to be part of the API. Those should all have a prefix of "_PL_" (is that
+legal?).
+
+The responsibility for contributions in this area are distributed among
+all interested parties.
+

+NSPR 2.0 libc functions
+-----------------------
+
+Last edited: AOF 04 March 1997
+
+This directory contains various libc-types of functions. All functions in
+this directory are platform independent, thread friendly (both safe and
+efficient). They are contributed from various sources, though the contri-
+butions are monitored by the NSPR group (mailto:freier).
+
+All API items exported by these functions will contain the same three
+character prefix, "PL_" (Portable Library). Internal function names
+that are not exported (static) are of little concern, though some caution
+must be used on those elements that are 'extern' but not really intended
+to be part of the API. Those should all have a prefix of "_PL_" (is that
+legal?).
+
+The responsibility for contributions in this area are distributed among
+all interested parties.
+

+** Name: thrashgc
+**
+** Description: test garbace collection functions.
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+ * They are only used in the PRMonitor functions.  Do not use them
+ * in new code.
+ *
+ * Unfortunately some of our clients depend on certain properties

+ * it by a portable implementation.
+ * - High-performance servers like the fact that PR_EnterMonitor
+ *   only calls PR_Lock and PR_ExitMonitor only calls PR_Unlock.
+ *   (A portable implementation would use a PRLock and a PRCondVar
+ *   to implement the recursive lock in a monitor and call both
+ *   PR_Lock and PR_Unlock in PR_EnterMonitor and PR_ExitMonitor.)
+ *   Unfortunately this forces us to read the monitor owner field
+ *   without holding a lock.
+ * - One way to make it safe to read the monitor owner field
+ *   without holding a lock is to make that field a PRThread*
+ *   (one should be able to read a pointer with a single machine
+ *   instruction).  However, PR_GetCurrentThread calls calloc if
+ *   it is called by a thread that was not created by NSPR.  The
+ *   malloc tracing tools in the Mozilla client use PRMonitor for
+ *   locking in their malloc, calloc, and free functions.  If
+ *   PR_EnterMonitor calls any of these functions, infinite

+** File:		pralarm.h
+** Description:	API to periodic alarms.
+**
+**
+** Alarms are defined to invoke some client specified function at 
+** a time in the future. The notification may be a one time event
+** or repeated at a fixed interval. The interval at which the next
+** notification takes place may be modified by the client code only
+** during the respective notification.
+**
+** The notification is delivered on a thread that is part of the
+** alarm context (PRAlarm). The thread will inherit the priority
+** of the Alarm creator.
+**
+** Any number of periodic alarms (PRAlarmID) may be created within
+** the context of a single alarm (PRAlarm). The notifications will be
+** scheduled as close to the desired time as possible.
+**
+** Repeating periodic notifies are expected to run at a fixed rate.
+** That rate is expressed as some number of notifies per period where
+** the period is much larger than a PRIntervalTime (see prinrval.h).

+**  
+** SIDE EFFECTS:
+**  A periodic notifier is created. The notifications will be delivered
+**  by the alarm's internal thread at a fixed interval whose rate is the
+**  number of interrupts per interval specified. The first notification
+**  will be delivered as soon as possible, and they will continue until
+**  the notifier routine indicates that they should cease of the alarm
+**  context is destroyed (PR_DestroyAlarm).
+** RESTRICTIONS:
+**  None. 
+** MEMORY:      Memory for the notifier object.
+** ALGORITHM:   The rate at which notifications are delivered are stated
+**              to be "'rate' notifies per 'interval'". The exact time of
+**              the notification is computed based on a epoch established
+**              when the notifier was set. Each notification is delivered
+**              not ealier than the epoch plus the fixed rate times the
+**              notification sequence number. Such notifications have the
+**              potential to be late by not more than 'interval'/'rate'.
+**              The amount of lateness of one notification is taken into
+**              account on the next in an attempt to avoid long term slew.

+** DESCRIPTION:
+**  Resets an existing alarm.
+** INPUTS:      PRAlarmID *id               Identify of the notifier.
+**              PRIntervalTime period       Interval over which the notifies
+**                                          are delivered.
+**              PRUint32 rate               The rate within the interval that
+**                                          the notifies will be delivered.
+** OUTPUTS:     None
+** RETURN:      PRStatus                    Indication of completion.
+**  
+** SIDE EFFECTS:
+**  An existing alarm may have its period and rate redefined. The
+**  additional side effect is that the notifier's epoch is recomputed.
+**  The first notification delivered by the newly refreshed alarm is
+**  defined to be 'interval'/'rate' from the time of the reset.
+** RESTRICTIONS:
+**  This function may only be called in the notifier for that alarm.
+** MEMORY:      N/A.
+** ALGORITHM:   See PR_SetAlarm().

+** DESCRIPTION:
+**
+** The call returns as soon as I/O is ready on one or more of the underlying
+** file/socket descriptors or an exceptional condition is pending. A count of the 
+** number of ready descriptors is returned unless a timeout occurs in which case 
+** zero is returned.  On return, PR_Select replaces the given descriptor sets with 
+** subsets consisting of those descriptors that are ready for the requested condition.
+** The total number of ready descriptors in all the sets is the return value.
+**

+**   PRInt32 num             
+**       This argument is unused but is provided for select(unix) interface
+**       compatability.  All input PR_fd_set arguments are self-describing
+**       with its own maximum number of elements in the set.

+**       Amount of time the call will block waiting for I/O to become ready. 
+**       If this time expires without any I/O becoming ready, the result will

+** prcountr.h -- NSPR Instrumentation counters
+**
+** The NSPR Counter Feature provides a means to "count
+** something." Counters can be dynamically defined, incremented,
+** decremented, set, and deleted under application program
+** control.
+** 																                   
+** The Counter Feature is intended to be used as instrumentation,                  
+** not as operational data. If you need a counter for operational                  
+** data, use native integral types.                                                
+** 																                   
+** Counters are 32bit unsigned intergers. On overflow, a counter                   
+** will wrap. No exception is recognized or reported.                              
+**                                                                                 
+** A counter can be dynamically created using a two level naming
+** convention. A "handle" is returned when the counter is
+** created. The counter can subsequently be addressed by its
+** handle. An API is provided to get an existing counter's handle
+** given the names with  which it was originally created. 
+** Similarly, a counter's name can be retrieved given its handle.
+** 
+** The counter naming convention is a two-level hierarchy. The
+** QName is the higher level of the hierarchy; RName is the
+** lower level. RNames can be thought of as existing within a
+** QName. The same RName can exist within multiple QNames. QNames
+** are unique. The NSPR Counter is not a near-zero overhead
+** feature. Application designers should be aware of 
+** serialization issues when using the Counter API. Creating a
+** counter locks a large asset, potentially causing a stall. This
+** suggest that applications should create counters at component
+** initialization, for example, and not create and destroy them
+** willy-nilly. ... You have been warned.
+** 
+** Incrementing and Adding to counters uses atomic operations.
+** The performance of these operations will vary from platform
+** to platform. On platforms where atomic operations are not
+** supported the overhead may be substantial.
+** 
+** When traversing the counter database with FindNext functions,
+** the instantaneous values of any given counter is that at the
+** moment of extraction. The state of the entire counter database
+** may not be viewed as atomic.
+** 
+** The counter interface may be disabled (No-Op'd) at compile
+** time. When DEBUG is defined at compile time, the Counter
+** Feature is compiled into NSPR and applications invoking it.
+** When DEBUG is not defined, the counter macros compile to
+** nothing. To force the Counter Feature to be compiled into an
+** optimized build, define FORCE_NSPR_COUNTERS at compile time
+** for both NSPR and the application intending to use it.
+** 
+** Application designers should use the macro form of the Counter
+** Feature methods to minimize performance impact in optimized
+** builds. The macros normally compile to nothing on optimized
+** builds.
+** 
+** Application designers should be aware of the effects of
+** debug and optimized build differences when using result of the
+** Counter Feature macros in expressions.
+** 
+** The Counter Feature is thread-safe and SMP safe.

+** PR_GetEnv() -- Retrieve value of environment variable
+** 
+** Description:
+** PR_GetEnv() is modeled on Unix getenv().
+** 
+** 
+** Inputs: 
+**   var -- The name of the environment variable
+** 
+** Returns:
+**   The value of the environment variable 'var' or NULL if
+** the variable is undefined.
+** 
+** Restrictions:
+**   You'd think that a POSIX getenv(), putenv() would be
+**   consistently implemented everywhere. Surprise! It is not. On
+**   some platforms, a putenv() where the argument is of
+**   the form "name"  causes the named environment variable to
+**   be un-set; that is: a subsequent getenv() returns NULL. On
+**   other platforms, the putenv() fails, on others, it is a
+**   no-op. Similarly, a putenv() where the argument is of the
+**   form "name=" causes the named environment variable to be
+**   un-set; a subsequent call to getenv() returns NULL. On
+**   other platforms, a subsequent call to getenv() returns a
+**   pointer to a null-string (a byte of zero).
+** 
+**   PR_GetEnv(), PR_SetEnv() provide a consistent behavior 
+**   across all supported platforms. There are, however, some
+**   restrictions and some practices you must use to achieve
+**   consistent results everywhere.
+** 
+**   When manipulating the environment there is no way to un-set
+**   an environment variable across all platforms. We suggest
+**   you interpret the return of a pointer to null-string to
+**   mean the same as a return of NULL from PR_GetEnv().
+** 
+**   A call to PR_SetEnv() where the parameter is of the form
+**   "name" will return PR_FAILURE; the environment remains
+**   unchanged. A call to PR_SetEnv() where the parameter is
+**   of the form "name=" may un-set the envrionment variable on
+**   some platforms; on others it may set the value of the
+**   environment variable to the null-string.
+** 
+**   For example, to test for NULL return or return of the
+**   null-string from PR_GetEnv(), use the following code
+**   fragment:
+** 
+**      char *val = PR_GetEnv("foo");
+**      if ((NULL == val) || ('\0' == *val)) { 
+**          ... interpret this as un-set ... 
+**      }
+** 
+**   The caller must ensure that the string passed
+**   to PR_SetEnv() is persistent. That is: The string should
+**   not be on the stack, where it can be overwritten
+**   on return from the function calling PR_SetEnv().
+**   Similarly, the string passed to PR_SetEnv() must not be
+**   overwritten by other actions of the process. ... Some
+**   platforms use the string by reference rather than copying
+**   it into the environment space. ... You have been warned!
+** 
+**   Use of platform-native functions that manipulate the
+**   environment (getenv(), putenv(), 
+**   SetEnvironmentVariable(), etc.) must not be used with
+**   NSPR's similar functions. The platform-native functions
+**   may not be thread safe and/or may operate on different
+**   conceptual environment space than that operated upon by
+**   NSPR's functions or other environment manipulating
+**   functions on the same platform. (!)

+** Description:	Localizable error code to string function.
+**
+**
+** NSPR provides a mechanism for converting an error code to a
+** descriptive string, in a caller-specified language.
+**
+** Error codes themselves are 32 bit (signed) integers.  Typically,
+** the high order 24 bits are an identifier of which error table the
+** error code is from, and the low order 8 bits are a sequential error
+** number within the table.  NSPR supports error tables whose first
+** error code is not a multiple of 256, such error code assignments
+** should be avoided when possible.
+**
+** Error table 0 is defined to match the UNIX system call error table
+** (sys_errlist); this allows errno values to be used directly in the
+** library.  Other error table numbers are typically formed by
+** compacting together the first four characters of the error table
+** name.  The mapping between characters in the name and numeric
+** values in the error code are defined in a system-independent
+** fashion, so that two systems that can pass integral values between
+** them can reliably pass error codes without loss of meaning; this
+** should work even if the character sets used are not the
+** same. (However, if this is to be done, error table 0 should be
+** avoided, since the local system call error tables may differ.)
+**
+** Libraries defining error codes need only provide a table mapping
+** error code numbers to names and default English descriptions,
+** calling a routine to install the table, making it ``known'' to NSPR
+** library.  Once installed, a table may not be removed.  Any error
+** code the library generates can be converted to the corresponding
+** error message.  There is also a default format for error codes
+** accidentally returned before making the table known, which is of
+** the form "unknown code foo 32", where "foo" would be the name of
+** the table.
+**
+** Normally, the error code conversion routine only supports the
+** languages "i-default" and "en", returning the error-table-provided
+** English description for both languages.  The application may
+** provide a localization plugin, allowing support for additional
+** languages.

+ *           INADDR_ANY, INADDR_LOOPBACK, INADDR_BROADCAST
+ *           ntohl(), ntohs(), htonl(), ntons().

+** Pollable events
+**
+** A pollable event is a special kind of file descriptor.
+** The only I/O operation you can perform on a pollable event
+** is to poll it with the PR_POLL_READ flag.  You can't
+** read from or write to a pollable event.
+**
+** The purpose of a pollable event is to combine event waiting
+** with I/O waiting in a single PR_Poll call.  Pollable events
+** are implemented using a pipe or a pair of TCP sockets
+** connected via the loopback address, therefore setting and
+** waiting for pollable events are expensive operating system
+** calls.  Do not use pollable events for general thread
+** synchronization. Use condition variables instead.
+**
+** A pollable event has two states: set and unset.  Events
+** are not queued, so there is no notion of an event count.
+** A pollable event is either set or unset.
+**
+** A new pollable event is created by a PR_NewPollableEvent
+** call and is initially in the unset state.
+**
+** PR_WaitForPollableEvent blocks the calling thread until
+** the pollable event is set, and then it atomically unsets
+** the pollable event before it returns.
+**
+** To set a pollable event, call PR_SetPollableEvent.
+**
+** One can call PR_Poll with the PR_POLL_READ flag on a pollable
+** event.  When the pollable event is set, PR_Poll returns with
+** the PR_POLL_READ flag set in the out_flags.

+*****  A Word about Model Dependent Function Naming Convention ***********
+*************************************************************************/
+
+/*
+NSPR 2.0 must implement its function across a range of platforms 
+including: MAC, Windows/16, Windows/95, Windows/NT, and several
+variants of Unix. Each implementation shares common code as well 
+as having platform dependent portions. This standard describes how
+the model dependent portions are to be implemented.
+
+In header file pr/include/primpl.h, each publicly declared 
+platform dependent function is declared as:
+
+NSPR_API void _PR_MD_FUNCTION( long arg1, long arg2 );
+#define _PR_MD_FUNCTION _MD_FUNCTION
+
+In header file pr/include/md/<platform>/_<platform>.h, 
+each #define'd macro is redefined as one of:
+
+#define _MD_FUNCTION <blanks>
+#define _MD_FUNCTION <expanded macro>
+#define _MD_FUNCTION <osFunction>
+#define _MD_FUNCTION <_MD_Function>
+
+Where:
+
+<blanks> is no definition at all. In this case, the function is not implemented 
+and is never called for this platform. 
+For example: 
+#define _MD_INIT_CPUS()
+
+<expanded macro> is a C language macro expansion. 
+For example: 
+#define        _MD_CLEAN_THREAD(_thread) \
+    PR_BEGIN_MACRO \
+        PR_DestroyCondVar(_thread->md.asyncIOCVar); \
+        PR_DestroyLock(_thread->md.asyncIOLock); \
+    PR_END_MACRO
+
+<osFunction> is some function implemented by the host operating system. 
+For example: 
+#define _MD_EXIT        exit
+
+<_MD_function> is the name of a function implemented for this platform in 
+pr/src/md/<platform>/<soruce>.c file. 
+For example: 
+#define        _MD_GETFILEINFO         _MD_GetFileInfo
+
+In <source>.c, the implementation is:

+/*
+** prlog.h -- Declare interfaces to NSPR's Logging service
+**
+** NSPR provides a logging service that is used by NSPR itself and is
+** available to client programs.
+**
+** To use the service from a client program, you should create a
+** PRLogModuleInfo structure by calling PR_NewLogModule(). After
+** creating the LogModule, you can write to the log using the PR_LOG()
+** macro.
+**
+** Initialization of the log service is handled by NSPR initialization.
+**
+** At execution time, you must enable the log service. To enable the
+** log service, set the environment variable: NSPR_LOG_MODULES
+** variable.
+**
+** NSPR_LOG_MODULES variable has the form:
+**
+**     <moduleName>:<value>[, <moduleName>:<value>]*
+**
+** Where:
+**  <moduleName> is the name passed to PR_NewLogModule().
+**  <value> is a numeric constant, e.g. 5. This value is the maximum
+** value of a log event, enumerated by PRLogModuleLevel, that you want
+** written to the log.
+** 
+** For example: to record all events of greater value than or equal to
+** PR_LOG_ERROR for a LogModule names "gizmo", say:
+** 
+** set NSPR_LOG_MODULES=gizmo:2
+** 
+** Note that you must specify the numeric value of PR_LOG_ERROR.
+** 
+** Special LogModule names are provided for controlling NSPR's log
+** service at execution time. These controls should be set in the
+** NSPR_LOG_MODULES environment variable at execution time to affect
+** NSPR's log service for your application.
+** 
+** The special LogModule "all" enables all LogModules. To enable all
+** LogModule calls to PR_LOG(), say:
+** 
+** set NSPR_LOG_MODULES=all:5
+** 
+** The special LogModule name "sync" tells the NSPR log service to do
+** unbuffered logging.
+** 
+** The special LogModule name "bufsize:<size>" tells NSPR to set the
+** log buffer to <size>.
+**
+** The environment variable NSPR_LOG_FILE specifies the log file to use
+** unless the default of "stderr" is acceptable. For MS Windows
+** systems, NSPR_LOG_FILE can be set to a special value: "WinDebug"
+** (case sensitive). This value causes PR_LOG() output to be written
+** using the Windows API OutputDebugString(). OutputDebugString()
+** writes to the debugger window; some people find this helpful.
+** 
+**
+** To put log messages in your programs, use the PR_LOG macro:
+**
+**     PR_LOG(<module>, <level>, (<printfString>, <args>*));
+**
+** Where <module> is the address of a PRLogModuleInfo structure, and
+** <level> is one of the levels defined by the enumeration:
+** PRLogModuleLevel. <args> is a printf() style of argument list. That
+** is: (fmtstring, ...).
+**
+** Example:
+** 
+** main() {
+**    PRIntn one = 1;
+**    PRLogModuleInfo * myLm = PR_NewLogModule("gizmo");
+**    PR_LOG( myLm, PR_LOG_ALWAYS, ("Log this! %d\n", one)); 
+**    return; 
+** }
+** 
+** Note the use of printf() style arguments as the third agrument(s) to
+** PR_LOG().
+** 
+** After compiling and linking you application, set the environment:
+** 
+** set NSPR_LOG_MODULES=gizmo:5
+** set NSPR_LOG_FILE=logfile.txt
+** 
+** When you execute your application, the string "Log this! 1" will be
+** written to the file "logfile.txt".
+** 
+** Note to NSPR engineers: a number of PRLogModuleInfo structures are
+** defined and initialized in prinit.c. See this module for ideas on
+** what to log where.

+** FUNCTION: PR_sscanf
+** DESCRIPTION:
+**     PR_sscanf() scans the input character string, performs data
+**     conversions, and stores the converted values in the data objects
+**     pointed to by its arguments according to the format control
+**     string.
+**
+**     PR_sscanf() behaves the same way as the sscanf() function in the
+**     Standard C Library (stdio.h), with the following exceptions:
+**     - PR_sscanf() handles the NSPR integer and floating point types,
+**       such as PRInt16, PRInt32, PRInt64, and PRFloat64, whereas
+**       sscanf() handles the standard C types like short, int, long,
+**       and double.
+**     - PR_sscanf() has no multibyte character support, while sscanf()
+**       does.
+** INPUTS:
+**     const char *buf
+**         a character string holding the input to scan
+**     const char *fmt
+**         the format control string for the conversions
+**     ...
+**         variable number of arguments, each of them is a pointer to
+**         a data object in which the converted value will be stored
+** OUTPUTS: none
+** RETURNS: PRInt32

+** RESTRICTIONS:

+** PR_GetRandomNoise() -- Get random noise from the host platform
+**
+** Description:
+** PR_GetRandomNoise() provides, depending on platform, a random value.
+** The length of the random value is dependent on platform and the
+** platform's ability to provide a random value at that moment.
+**
+** The intent of PR_GetRandomNoise() is to provide a "seed" value for a
+** another random number generator that may be suitable for
+** cryptographic operations. This implies that the random value
+** provided may not be, by itself, cryptographically secure. The value
+** generated by PR_GetRandomNoise() is at best, extremely difficult to
+** predict and is as non-deterministic as the underlying platfrom can
+** provide.
+**
+** Inputs:
+**   buf -- pointer to a caller supplied buffer to contain the
+**          generated random number. buf must be at least as large as
+**          is specified in the 'size' argument.
+**
+**   size -- the requested size of the generated random number
+**
+** Outputs:
+**   a random number provided in 'buf'.
+**
+** Returns:
+**   PRSize value equal to the size of the random number actually
+**   generated, or zero. The generated size may be less than the size
+**   requested. A return value of zero means that PR_GetRandomNoise() is
+**   not implemented on this platform, or there is no available noise
+**   available to be returned at the time of the call.
+**
+** Restrictions:
+**   Calls to PR_GetRandomNoise() may use a lot of CPU on some platforms.
+**   Some platforms may block for up to a few seconds while they
+**   accumulate some noise. Busy machines generate lots of noise, but
+**   care is advised when using PR_GetRandomNoise() frequently in your
+**   application.
+**
+** History:
+**   Parts of the model dependent implementation for PR_GetRandomNoise()
+**   were taken in whole or part from code previously in Netscape's NSS
+**   component.

+** prshm.h -- NSPR Shared Memory
+**
+** NSPR Named Shared Memory API provides a cross-platform named
+** shared-memory interface. NSPR Named Shared Memory is modeled on
+** similar constructs in Unix and Windows operating systems. Shared
+** memory allows multiple processes to access one or more common shared
+** memory regions, using it as an inter-process communication channel.
+**
+** Notes on Platform Independence:
+**   NSPR Named Shared Memory is built on the native services offered
+**   by most platforms. The NSPR Named Shared Memory API tries to
+**   provide a least common denominator interface so that it works
+**   across all supported platforms. To ensure that it works everywhere,
+**   some platform considerations must be accomodated and the protocol
+**   for using NSPR Shared Memory API must be observed.
+**
+** Protocol:
+**   Multiple shared memories can be created using NSPR's Shared Memory
+**   feature. For each named shared memory, as defined by the name
+**   given in the PR_OpenSharedMemory() call, a protocol for using the
+**   shared memory API is required to ensure desired behavior. Failing
+**   to follow the protocol may yield unpredictable results.
+**   
+**   PR_OpenSharedMemory() will create the shared memory segment, if it
+**   does not already exist, or open a connection that the existing
+**   shared memory segment if it already exists.
+**   
+**   PR_AttachSharedMemory() should be called following
+**   PR_OpenSharedMemory() to map the memory segment to an address in
+**   the application's address space.
+**   
+**   PR_AttachSharedMemory() may be called to re-map a shared memory
+**   segment after detaching the same PRSharedMemory object. Be
+**   sure to detach it when done.
+**   
+**   PR_DetachSharedMemory() should be called to un-map the shared
+**   memory segment from the application's address space.
+**   
+**   PR_CloseSharedMemory() should be called when no further use of the
+**   PRSharedMemory object is required within a process. Following a
+**   call to  PR_CloseSharedMemory() the PRSharedMemory object is
+**   invalid and cannot be reused.
+**   
+**   PR_DeleteSharedMemory() should be called before process
+**   termination. After calling PR_DeleteSharedMemory() any further use
+**   of the shared memory associated with the name may cause
+**   unpredictable results.
+**   
+** Files:
+**   The name passed to PR_OpenSharedMemory() should be a valid filename
+**   for a unix platform. PR_OpenSharedMemory() creates file using the
+**   name passed in. Some platforms may mangle the name before creating
+**   the file and the shared memory.
+**   
+**   The unix implementation may use SysV IPC shared memory, Posix
+**   shared memory, or memory mapped files; the filename may used to
+**   define the namespace. On Windows, the name is significant, but
+**   there is no file associated with name.
+**   
+**   No assumptions about the persistence of data in the named file
+**   should be made. Depending on platform, the shared memory may be
+**   mapped onto system paging space and be discarded at process
+**   termination.
+**   
+**   All names provided to PR_OpenSharedMemory() should be valid
+**   filename syntax or name syntax for shared memory for the target
+**   platform. Referenced directories should have permissions 
+**   appropriate for writing.
+**
+** Limits:
+**   Different platforms have limits on both the number and size of
+**   shared memory resources. The default system limits on some
+**   platforms may be smaller than your requirements. These limits may
+**   be adjusted on some platforms either via boot-time options or by
+**   setting the size of the system paging space to accomodate more
+**   and/or larger shared memory segment(s).
+**
+** Security:
+**   On unix platforms, depending on implementation, contents of the
+**   backing store for the shared memory can be exposed via the file
+**   system. Set permissions and or access controls at create and attach
+**   time to ensure you get the desired security.
+**
+**   On windows platforms, no special security measures are provided.
+**
+** Example:
+**   The test case pr/tests/nameshm1.c provides an example of use as
+**   well as testing the operation of NSPR's Named Shared Memory.
+**
+** lth. 18-Aug-1999.

+** prshma.h -- NSPR Anonymous Shared Memory
+**
+** NSPR provides an anonymous shared memory based on NSPR's PRFileMap
+** type. The anonymous file-mapped shared memory provides an inheritable
+** shared memory, as in: the child process inherits the shared memory.
+** Compare the file-mapped anonymous shared memory to to a named shared
+** memory described in prshm.h. The intent is to provide a shared
+** memory that is accessable only by parent and child processes. ...
+** It's a security thing.
+** 
+** Depending on the underlying platform, the file-mapped shared memory
+** may be backed by a file. ... surprise! ... On some platforms, no
+** real file backs the shared memory. On platforms where the shared
+** memory is backed by a file, the file's name in the filesystem is
+** visible to other processes for only the duration of the creation of
+** the file, hopefully a very short time. This restricts processess
+** that do not inherit the shared memory from opening the file and
+** reading or writing its contents. Further, when all processes
+** using an anonymous shared memory terminate, the backing file is
+** deleted. ... If you are not paranoid, you're not paying attention.
+** 
+** The file-mapped shared memory requires a protocol for the parent
+** process and child process to share the memory. NSPR provides two
+** protocols. Use one or the other; don't mix and match.
+** 
+** In the first protocol, the job of passing the inheritable shared
+** memory is done via helper-functions with PR_CreateProcess(). In the
+** second protocol, the parent process is responsible for creating the
+** child process; the parent and child are mutually responsible for
+** passing a FileMap string. NSPR provides helper functions for
+** extracting data from the PRFileMap object. ... See the examples
+** below.
+** 
+** Both sides should adhere strictly to the protocol for proper
+** operation. The pseudo-code below shows the use of a file-mapped
+** shared memory by a parent and child processes. In the examples, the
+** server creates the file-mapped shared memory, the client attaches to
+** it.
+**
+** First protocol.
+** Server:
+**
+**   fm = PR_OpenAnonFileMap(dirName, size, FilemapProt); 
+**   addr = PR_MemMap(fm); 
+**   attr = PR_NewProcessAttr();
+**   PR_ProcessAttrSetInheritableFileMap( attr, fm, shmname );
+**   PR_CreateProcess(Client); 
+**   PR_DestroyProcessAttr(attr);
+**   ... yadda ...
+**   PR_MemUnmap( addr );
+**   PR_CloseFileMap(fm);
+**
+**
+** Client: 
+**   ... started by server via PR_CreateProcess()
+**   fm = PR_GetInheritedFileMap( shmname );
+**   addr = PR_MemMap(fm);
+**   ... yadda ...
+**   PR_MemUnmap(addr);
+**   PR_CloseFileMap(fm);
+**
+**
+** Second Protocol:
+** Server:
+**
+**   fm = PR_OpenAnonFileMap(dirName, size, FilemapProt); 
+**   fmstring = PR_ExportFileMapAsString( fm );
+**   addr = PR_MemMap(fm); 
+**    ... application specific technique to pass fmstring to child
+**    ... yadda ... Server uses his own magic to create child
+**   PR_MemUnmap( addr );
+**   PR_CloseFileMap(fm);
+**
+**
+** Client: 
+**   ... started by server via his own magic
+**   ... application specific technique to find fmstring from parent
+**   fm = PR_ImportFileMapFromString( fmstring )
+**   addr = PR_MemMap(fm);
+**   ... yadda ...
+**   PR_MemUnmap(addr);
+**   PR_CloseFileMap(fm);
+**
+**
+** lth. 2-Jul-1999.
+**
+** Note: The second protocol was requested by NelsonB (7/1999); this is
+** to accomodate servers which already create their own child processes
+** using platform native methods.

+** API for NSPR threads. On some architectures (Mac OS Classic
+** notably) pre-emptibility is not guaranteed. Hard priority scheduling
+** is not guaranteed, so programming using priority based synchronization
+** is a no-no.
+**
+** NSPR threads are scheduled based loosely on their client set priority.
+** In general, a thread of a higher priority has a statistically better
+** chance of running relative to threads of lower priority. However,
+** NSPR uses multiple strategies to provide execution vehicles for thread
+** abstraction of various host platforms. As it turns out, there is little
+** NSPR can do to affect the scheduling attributes of "GLOBAL" threads.
+** However, a semblance of GLOBAL threads is used to implement "LOCAL"
+** threads. An arbitrary number of such LOCAL threads can be assigned to
+** a single GLOBAL thread.
+**
+** For scheduling, NSPR will attempt to run the highest priority LOCAL
+** thread associated with a given GLOBAL thread. It is further assumed
+** that the host OS will apply some form of "fair" scheduling on the
+** GLOBAL threads.
+**
+** Threads have a "system flag" which when set indicates the thread
+** doesn't count for determining when the process should exit (the
+** process exits when the last user thread exits).
+**
+** Threads also have a "scope flag" which controls whether the threads
+** are scheduled in the local scope or scheduled by the OS globally. This 
+** indicates whether a thread is permanently bound to a native OS thread. 
+** An unbound thread competes for scheduling resources in the same process.
+**
+** Another flag is "state flag" which control whether the thread is joinable.
+** It allows other threads to wait for the created thread to reach completion.
+**
+** Threads can have "per-thread-data" attached to them. Each thread has a
+** per-thread error number and error string which are updated when NSPR
+** operations fail.

+**
+** Prototypes and macros used to make up for deficiencies that we have found
+** in ANSI environments.
+**
+** Since we do not wrap <stdlib.h> and all the other standard headers, authors
+** of portable code will not know in general that they need these definitions.
+** Instead of requiring these authors to find the dependent uses in their code
+** and take the following steps only in those C files, we take steps once here
+** for all C files.

+** MACROS:      PR_EXTERN
+**              PR_IMPLEMENT
+** DESCRIPTION:
+**      These are only for externally visible routines and globals.  For
+**      internal routines, just use "extern" for type checking and that
+**      will not export internal cross-file or forward-declared symbols.
+**      Define a macro for declaring procedures return types. We use this to
+**      deal with windoze specific type hackery for DLL definitions. Use
+**      PR_EXTERN when the prototype for the method is declared. Use
+**      PR_IMPLEMENT for the implementation of the method.
+**
+** Example:
+**   in dowhim.h
+**     PR_EXTERN( void ) DoWhatIMean( void );
+**   in dowhim.c
+**     PR_IMPLEMENT( void ) DoWhatIMean( void ) { return; }

+** To get stdio to work for Win16, all calls to printf() and related
+** things must be called from the environment of the .EXE; calls to
+** printf() from the .DLL send output to the bit-bucket.
+**
+** To make sure that PR_fprintf(), and related functions, work correctly,
+** the actual stream I/O to stdout, stderr, stdin must be done in the
+** .EXE. To do this, a hack is placed in _MD_Write() such that the
+** fd for stdio handles results in a call to the .EXE.
+**
+** file w16stdio.c contains the functions that get called from NSPR
+** to do the actual I/O. w16stdio.o must be statically linked with
+** any application needing stdio for Win16.
+**
+** The address of these functions must be made available to the .DLL
+** so he can call back to the .EXE. To do this, function 
+** PR_MD_RegisterW16StdioCallbacks() is called from the .EXE.
+** The arguments are the functions defined in w16stdio.c
+** At runtime, MD_Write() calls the registered functions, if any
+** were registered.
+**
+** prinit.h contains a macro PR_STDIO_INIT() that calls the registration
+** function for Win16; For other platforms, the macro is a No-Op.
+**
+** Note that stdio is not operational at all on Win16 GUI applications.
+** This special case exists to provide stdio capability from the NSPR
+** .DLL for command line applications only. NSPR's test cases are
+** almost exclusively command line applications.

+** Name: ranfile.c

+** Description: Test to hammer on various components of NSPR
+** Modification History:
+** 20-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+** NSPR_FD_CACHE_SIZE_LOW and NSPR_FD_CACHE_SIZE_HIGH. The former sets

+** To avoid this unfortunate case, we use the low level locking

+     * robm says:
+     *     This version has some problems which need to be addressed.
+     *     First, intercept all system calls and prevent them from
+     *     executing the library code which performs stack switches
+     *     before normal system call invocation.  In order for library
+     *     calls which make system calls to work (like stdio), however,
+     *     we must also allocate our own stack and switch the primordial
+     *     stack to use it. This isn't so bad, except that I fudged the
+     *     backtrace length when copying the old stack to the new one.
+     *
+     * This is the original comment of robm in the code:
+     *    XXXrobm Horrific. To avoid a problem with HP's system call
+     *    code, we allocate a new stack for the primordial thread and
+     *    use it. However, we don't know how far back the original stack
+     *    goes. We should create a routine that performs a backtrace and
+     *    finds out just how much we need to copy. As a temporary measure,
+     *    I just copy an arbitrary guess.
+     *
+     * In an email to servereng dated 2 Jan 1997, Mike Patnode (mikep)
+     * suggests that this only needs to be done for HP-UX 9.

+!  assumed to be volatile during calls.
+!

+/* Windows NT IO module
+ *
+ * This module handles IO for LOCAL_SCOPE and GLOBAL_SCOPE threads.
+ * For LOCAL_SCOPE threads, we're using NT fibers.  For GLOBAL_SCOPE threads
+ * we're using NT-native threads.
+ *
+ * When doing IO, we want to use completion ports for optimal performance 
+ * with fibers.  But if we use completion ports for all IO, it is difficult
+ * to project a blocking model with GLOBAL_SCOPE threads.  To handle this
+ * we create an extra thread for completing IO for GLOBAL_SCOPE threads.
+ * We don't really want to complete IO on a separate thread for LOCAL_SCOPE
+ * threads because it means extra context switches, which are really slow
+ * on NT...  Since we're using a single completion port, some IO will
+ * be incorrectly completed on the GLOBAL_SCOPE IO thread; this will mean
+ * extra context switching; but I don't think there is anything I can do
+ * about it.

+** Lockfile hacks
+**
+** The following code is a hack to work around a microsoft bug with lockfile.
+** The problem is that on NT 3.51, if LockFileEx() succeeds, you never
+** get a completion back for files that are on local disks.  So, we need to
+** know if a file is local or remote so we can tell if we should expect 
+** a completion.
+**
+** The only way to check if a file is local or remote based on the handle is
+** to get the serial number for the volume it is mounted on and then to 
+** compare that with mounted drives.  This code caches the volume numbers of
+** fixed disks and does a relatively quick check.
+**
+** Locking:  Since the only thing we ever do when multithreaded is a 32bit
+**           assignment, we probably don't need locking.  It is included just
+**           case anyway.
+**
+** Limitations:  Does not work on floppies because they are too slow
+**               Unknown if it will work on wierdo 3rd party file systems

+ * On Win32, we map three kinds of error codes:
+ * - GetLastError(): for Win32 functions
+ * - WSAGetLastError(): for Winsock functions
+ * - errno: for standard C library functions
+ * 
+ * GetLastError() and WSAGetLastError() return error codes in
+ * non-overlapping ranges, so their error codes (ERROR_* and
+ * WSAE*) can be mapped by the same function.  On the other hand,
+ * errno and GetLastError() have overlapping ranges, so we need
+ * to use a separate function to map errno.
+ *
+ * We do not check for WSAEINPROGRESS and WSAEINTR because we do not
+ * use blocking Winsock 1.1 calls.
+ *
+ * Except for the 'socket' call, we do not check for WSAEINITIALISED.
+ * It is assumed that if Winsock is not initialized, that fact will
+ * be detected at the time we create new sockets.

+/* On a machine with IEEE extended-precision registers, it is

+ * before invoking strtod or dtoa.  If the machine uses (the equivalent
+ * of) Intel 80x87 arithmetic, the call
+ *	_control87(PC_53, MCW_PC);

+
+/* strtod for IEEE-, VAX-, and IBM-arithmetic machines.
+ *
+ * This strtod returns a nearest machine number to the input decimal
+ * string (or sets errno to ERANGE).  With IEEE arithmetic, ties are
+ * broken by the IEEE round-even rule.  Otherwise ties are broken by
+ * biased rounding (add half and chop).
+ *
+ * Inspired loosely by William D. Clinger's paper "How to Read Floating
+ * Point Numbers Accurately" [Proc. ACM SIGPLAN '90, pp. 92-101].
+ *
+ * Modifications:
+ *
+ *	1. We only require IEEE, IBM, or VAX double-precision
+ *		arithmetic (not IEEE double-extended).
+ *	2. We get by with floating-point arithmetic in a case that
+ *		Clinger missed -- when we're computing d * 10^n
+ *		for a small integer d and the integer n is not too
+ *		much larger than 22 (the maximum integer k for which
+ *		we can represent 10^k exactly), we may be able to
+ *		compute (d*10^k) * 10^(e-k) with just one roundoff.
+ *	3. Rather than a bit-at-a-time adjustment of the binary
+ *		result in the hard case, we use floating-point
+ *		arithmetic to determine the adjustment to within
+ *		one bit; only in really hard cases do we need to
+ *		compute a second residual.
+ *	4. Because of 3., we don't need a large table of powers of 10
+ *		for ten-to-e (just some small tables, e.g. of 10^k
+ *		for 0 <= k <= 22).

+
+/*
+ * #define IEEE_8087 for IEEE-arithmetic machines where the least
+ *	significant byte has the lowest address.
+ * #define IEEE_MC68k for IEEE-arithmetic machines where the most
+ *	significant byte has the lowest address.
+ * #define Long int on machines with 32-bit ints and 64-bit longs.
+ * #define IBM for IBM mainframe-style floating-point arithmetic.
+ * #define VAX for VAX-style floating-point arithmetic (D_floating).
+ * #define No_leftright to omit left-right logic in fast floating-point
+ *	computation of dtoa.
+ * #define Honor_FLT_ROUNDS if FLT_ROUNDS can assume the values 2 or 3
+ *	and strtod and dtoa should round accordingly.  Unless Trust_FLT_ROUNDS
+ *	is also #defined, fegetround() will be queried for the rounding mode.
+ *	Note that both FLT_ROUNDS and fegetround() are specified by the C99
+ *	standard (and are specified to be consistent, with fesetround()
+ *	affecting the value of FLT_ROUNDS), but that some (Linux) systems
+ *	do not work correctly in this regard, so using fegetround() is more
+ *	portable than using FLT_FOUNDS directly.
+ * #define Check_FLT_ROUNDS if FLT_ROUNDS can assume the values 2 or 3
+ *	and Honor_FLT_ROUNDS is not #defined.
+ * #define RND_PRODQUOT to use rnd_prod and rnd_quot (assembly routines
+ *	that use extended-precision instructions to compute rounded
+ *	products and quotients) with IBM.
+ * #define ROUND_BIASED for IEEE-format with biased rounding.
+ * #define Inaccurate_Divide for IEEE-format with correctly rounded
+ *	products but inaccurate quotients, e.g., for Intel i860.
+ * #define NO_LONG_LONG on machines that do not have a "long long"
+ *	integer type (of >= 64 bits).  On such machines, you can
+ *	#define Just_16 to store 16 bits per 32-bit Long when doing
+ *	high-precision integer arithmetic.  Whether this speeds things
+ *	up or slows things down depends on the machine and the number
+ *	being converted.  If long long is available and the name is
+ *	something other than "long long", #define Llong to be the name,
+ *	and if "unsigned Llong" does not work as an unsigned version of
+ *	Llong, #define #ULLong to be the corresponding unsigned type.
+ * #define KR_headers for old-style C function headers.
+ * #define Bad_float_h if your system lacks a float.h or if it does not
+ *	define some or all of DBL_DIG, DBL_MAX_10_EXP, DBL_MAX_EXP,
+ *	FLT_RADIX, FLT_ROUNDS, and DBL_MAX.
+ * #define MALLOC your_malloc, where your_malloc(n) acts like malloc(n)
+ *	if memory is available and otherwise does something you deem
+ *	appropriate.  If MALLOC is undefined, malloc will be invoked
+ *	directly -- and assumed always to succeed.  Similarly, if you
+ *	want something other than the system's free() to be called to
+ *	recycle memory acquired from MALLOC, #define FREE to be the
+ *	name of the alternate routine.  (FREE or free is only called in
+ *	pathological cases, e.g., in a dtoa call after a dtoa return in
+ *	mode 3 with thousands of digits requested.)
+ * #define Omit_Private_Memory to omit logic (added Jan. 1998) for making
+ *	memory allocations from a private pool of memory when possible.
+ *	When used, the private pool is PRIVATE_MEM bytes long:  2304 bytes,
+ *	unless #defined to be a different length.  This default length
+ *	suffices to get rid of MALLOC calls except for unusual cases,
+ *	such as decimal-to-binary conversion of a very long string of
+ *	digits.  The longest string dtoa can return is about 751 bytes
+ *	long.  For conversions by strtod of strings of 800 digits and
+ *	all dtoa conversions in single-threaded executions with 8-byte
+ *	pointers, PRIVATE_MEM >= 7400 appears to suffice; with 4-byte
+ *	pointers, PRIVATE_MEM >= 7112 appears adequate.
+ * #define NO_INFNAN_CHECK if you do not wish to have INFNAN_CHECK
+ *	#defined automatically on IEEE systems.  On such systems,
+ *	when INFNAN_CHECK is #defined, strtod checks
+ *	for Infinity and NaN (case insensitively).  On some systems
+ *	(e.g., some HP systems), it may be necessary to #define NAN_WORD0
+ *	appropriately -- to the most significant word of a quiet NaN.
+ *	(On HP Series 700/800 machines, -DNAN_WORD0=0x7ff40000 works.)
+ *	When INFNAN_CHECK is #defined and No_Hex_NaN is not #defined,
+ *	strtod also accepts (case insensitively) strings of the form
+ *	NaN(x), where x is a string of hexadecimal digits and spaces;
+ *	if there is only one string of hexadecimal digits, it is taken
+ *	for the 52 fraction bits of the resulting NaN; if there are two
+ *	or more strings of hex digits, the first is for the high 20 bits,
+ *	the second and subsequent for the low 32 bits, with intervening
+ *	white space ignored; but if this results in none of the 52
+ *	fraction bits being on (an IEEE Infinity symbol), then NAN_WORD0
+ *	and NAN_WORD1 are used instead.
+ * #define MULTIPLE_THREADS if the system offers preemptively scheduled
+ *	multiple threads.  In this case, you must provide (or suitably
+ *	#define) two locks, acquired by ACQUIRE_DTOA_LOCK(n) and freed
+ *	by FREE_DTOA_LOCK(n) for n = 0 or 1.  (The second lock, accessed
+ *	in pow5mult, ensures lazy evaluation of only one copy of high
+ *	powers of 5; omitting this lock would introduce a small
+ *	probability of wasting memory, but would otherwise be harmless.)
+ *	You must also invoke freedtoa(s) to free the value s returned by
+ *	dtoa.  You may do so whether or not MULTIPLE_THREADS is #defined.
+ * #define NO_IEEE_Scale to disable new (Feb. 1997) logic in strtod that
+ *	avoids underflows on inputs whose result does not underflow.
+ *	If you #define NO_IEEE_Scale on a machine that uses IEEE-format
+ *	floating-point numbers and flushes underflows to zero rather
+ *	than implementing gradual underflow, then you must also #define
+ *	Sudden_Underflow.
+ * #define USE_LOCALE to use the current locale's decimal_point value.
+ * #define SET_INEXACT if IEEE arithmetic is being used and extra
+ *	computation should be done to set the inexact flag when the
+ *	result is inexact and avoid setting inexact when the result
+ *	is exact.  In this case, dtoa.c must be compiled in
+ *	an environment, perhaps provided by #include "dtoa.c" in a
+ *	suitable wrapper, that defines two functions,
+ *		int get_inexact(void);
+ *		void clear_inexact(void);
+ *	such that get_inexact() returns a nonzero value if the
+ *	inexact bit is already set, and clear_inexact() sets the
+ *	inexact bit to 0.  When SET_INEXACT is #defined, strtod
+ *	also does extra computations to set the underflow and overflow
+ *	flags when appropriate (i.e., when the result is tiny and
+ *	inexact or when it is a numeric value rounded to +-infinity).
+ * #define NO_ERRNO if strtod should not assign errno = ERANGE when
+ *	the result overflows to +-Infinity or underflows to 0.
+ * #define NO_HEX_FP to omit recognition of hexadecimal floating-point
+ *	values by strtod.
+ * #define NO_STRTOD_BIGCOMP (on IEEE-arithmetic systems only for now)
+ *	to disable logic for "fast" testing of very long input strings
+ *	to strtod.  This testing proceeds by initially truncating the
+ *	input string, then if necessary comparing the whole string with
+ *	a decimal expansion to decide close cases. This logic is only
+ *	used for input more than STRTOD_DIGLIM digits long (default 40).

+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 112-126].
+ *
+ * Modifications:
+ *	1. Rather than iterating, we use a simple numeric overestimate
+ *	   to determine k = floor(log10(d)).  We scale relevant
+ *	   quantities using O(log2(k)) rather than O(k) multiplications.
+ *	2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
+ *	   try to generate digits strictly left to right.  Instead, we
+ *	   compute with fewer bits and propagate the carry if necessary
+ *	   when rounding the final digit up.  This is often faster.
+ *	3. Under the assumption that input will be rounded nearest,
+ *	   mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ *	   That is, we allow equality in stopping tests when the
+ *	   round-nearest rule will give the same floating-point value
+ *	   as would satisfaction of the stopping test with strict
+ *	   inequality.
+ *	4. We remove common factors of powers of 2 from relevant
+ *	   quantities.
+ *	5. When converting floating-point integers less than 1e16,
+ *	   we use floating-point arithmetic rather than resorting
+ *	   to multiple-precision integers.
+ *	6. When asked to produce fewer than 15 digits, we first try
+ *	   to get by with floating-point arithmetic; we resort to
+ *	   multiple-precision integer arithmetic only if we cannot
+ *	   guarantee that the floating-point calculation has given
+ *	   the correctly rounded result.  For k requested digits and
+ *	   "uniformly" distributed input, the probability is
+ *	   something like 10^(k-15) that we must resort to the Long
+ *	   calculation.

+** prcountr.c -- NSPR Instrumentation Counters
+**
+** Implement the interface defined in prcountr.h
+**
+** Design Notes:
+**
+** The Counter Facility (CF) has a single anchor: qNameList.      
+** The anchor is a PRCList. qNameList is a list of links in QName
+** structures. From qNameList any QName structure and its
+** associated RName structure can be located. 
+** 
+** For each QName, a list of RName structures is anchored at
+** rnLink in the QName structure.
+** 
+** The counter itself is embedded in the RName structure.
+** 
+** For manipulating the counter database, single lock is used to
+** protect the entire list: counterLock.
+**
+** A PRCounterHandle, defined in prcountr.h, is really a pointer
+** to a RName structure. References by PRCounterHandle are
+** dead-reconed to the RName structure. The PRCounterHandle is
+** "overloaded" for traversing the QName structures; only the
+** function PR_FindNextQnameHandle() uses this overloading.
+**
+** 
+** ToDo (lth): decide on how to lock or atomically update
+** individual counters. Candidates are: the global lock; a lock
+** per RName structure; Atomic operations (Note that there are
+** not adaquate atomic operations (yet) to achieve this goal). At
+** this writing (6/19/98) , the update of the counter variable in
+** a QName structure is unprotected.

+ *	1. We only require IEEE, IBM, or VAX double-precision
+ *		arithmetic (not IEEE double-extended).
+ *	2. We get by with floating-point arithmetic in a case that
+ *		Clinger missed -- when we're computing d * 10^n
+ *		for a small integer d and the integer n is not too
+ *		much larger than 22 (the maximum integer k for which
+ *		we can represent 10^k exactly), we may be able to
+ *		compute (d*10^k) * 10^(e-k) with just one roundoff.
+ *	3. Rather than a bit-at-a-time adjustment of the binary
+ *		result in the hard case, we use floating-point
+ *		arithmetic to determine the adjustment to within
+ *		one bit; only in really hard cases do we need to
+ *		compute a second residual.
+ *	4. Because of 3., we don't need a large table of powers of 10
+ *		for ten-to-e (just some small tables, e.g. of 10^k
+ *		for 0 <= k <= 22).

+/*
+ * #define IEEE_8087 for IEEE-arithmetic machines where the least
+ *	significant byte has the lowest address.
+ * #define IEEE_MC68k for IEEE-arithmetic machines where the most
+ *	significant byte has the lowest address.
+ * #define IEEE_ARM for IEEE-arithmetic machines where the two words
+ *	in a double are stored in big endian order but the two shorts
+ *	in a word are still stored in little endian order.
+ * #define Long int on machines with 32-bit ints and 64-bit longs.
+ * #define IBM for IBM mainframe-style floating-point arithmetic.
+ * #define VAX for VAX-style floating-point arithmetic (D_floating).
+ * #define No_leftright to omit left-right logic in fast floating-point
+ *	computation of dtoa.
+ * #define Honor_FLT_ROUNDS if FLT_ROUNDS can assume the values 2 or 3
+ *	and strtod and dtoa should round accordingly.
+ * #define Check_FLT_ROUNDS if FLT_ROUNDS can assume the values 2 or 3
+ *	and Honor_FLT_ROUNDS is not #defined.
+ * #define RND_PRODQUOT to use rnd_prod and rnd_quot (assembly routines
+ *	that use extended-precision instructions to compute rounded
+ *	products and quotients) with IBM.
+ * #define ROUND_BIASED for IEEE-format with biased rounding.
+ * #define Inaccurate_Divide for IEEE-format with correctly rounded
+ *	products but inaccurate quotients, e.g., for Intel i860.
+ * #define NO_LONG_LONG on machines that do not have a "long long"
+ *	integer type (of >= 64 bits).  On such machines, you can
+ *	#define Just_16 to store 16 bits per 32-bit Long when doing
+ *	high-precision integer arithmetic.  Whether this speeds things
+ *	up or slows things down depends on the machine and the number
+ *	being converted.  If long long is available and the name is
+ *	something other than "long long", #define Llong to be the name,
+ *	and if "unsigned Llong" does not work as an unsigned version of
+ *	Llong, #define #ULLong to be the corresponding unsigned type.
+ * #define KR_headers for old-style C function headers.
+ * #define Bad_float_h if your system lacks a float.h or if it does not
+ *	define some or all of DBL_DIG, DBL_MAX_10_EXP, DBL_MAX_EXP,
+ *	FLT_RADIX, FLT_ROUNDS, and DBL_MAX.
+ * #define MALLOC your_malloc, where your_malloc(n) acts like malloc(n)
+ *	if memory is available and otherwise does something you deem
+ *	appropriate.  If MALLOC is undefined, malloc will be invoked
+ *	directly -- and assumed always to succeed.  Similarly, if you
+ *	want something other than the system's free() to be called to
+ *	recycle memory acquired from MALLOC, #define FREE to be the
+ *	name of the alternate routine.  (FREE or free is only called in
+ *	pathological cases, e.g., in a dtoa call after a dtoa return in
+ *	mode 3 with thousands of digits requested.)
+ * #define Omit_Private_Memory to omit logic (added Jan. 1998) for making
+ *	memory allocations from a private pool of memory when possible.
+ *	When used, the private pool is PRIVATE_MEM bytes long:  2304 bytes,
+ *	unless #defined to be a different length.  This default length
+ *	suffices to get rid of MALLOC calls except for unusual cases,
+ *	such as decimal-to-binary conversion of a very long string of
+ *	digits.  The longest string dtoa can return is about 751 bytes
+ *	long.  For conversions by strtod of strings of 800 digits and
+ *	all dtoa conversions in single-threaded executions with 8-byte
+ *	pointers, PRIVATE_MEM >= 7400 appears to suffice; with 4-byte
+ *	pointers, PRIVATE_MEM >= 7112 appears adequate.
+ * #define INFNAN_CHECK on IEEE systems to cause strtod to check for
+ *	Infinity and NaN (case insensitively).  On some systems (e.g.,
+ *	some HP systems), it may be necessary to #define NAN_WORD0
+ *	appropriately -- to the most significant word of a quiet NaN.
+ *	(On HP Series 700/800 machines, -DNAN_WORD0=0x7ff40000 works.)
+ *	When INFNAN_CHECK is #defined and No_Hex_NaN is not #defined,
+ *	strtod also accepts (case insensitively) strings of the form
+ *	NaN(x), where x is a string of hexadecimal digits and spaces;
+ *	if there is only one string of hexadecimal digits, it is taken
+ *	for the 52 fraction bits of the resulting NaN; if there are two
+ *	or more strings of hex digits, the first is for the high 20 bits,
+ *	the second and subsequent for the low 32 bits, with intervening
+ *	white space ignored; but if this results in none of the 52
+ *	fraction bits being on (an IEEE Infinity symbol), then NAN_WORD0
+ *	and NAN_WORD1 are used instead.
+ * #define MULTIPLE_THREADS if the system offers preemptively scheduled
+ *	multiple threads.  In this case, you must provide (or suitably
+ *	#define) two locks, acquired by ACQUIRE_DTOA_LOCK(n) and freed
+ *	by FREE_DTOA_LOCK(n) for n = 0 or 1.  (The second lock, accessed
+ *	in pow5mult, ensures lazy evaluation of only one copy of high
+ *	powers of 5; omitting this lock would introduce a small
+ *	probability of wasting memory, but would otherwise be harmless.)
+ *	You must also invoke freedtoa(s) to free the value s returned by
+ *	dtoa.  You may do so whether or not MULTIPLE_THREADS is #defined.
+ * #define NO_IEEE_Scale to disable new (Feb. 1997) logic in strtod that
+ *	avoids underflows on inputs whose result does not underflow.
+ *	If you #define NO_IEEE_Scale on a machine that uses IEEE-format
+ *	floating-point numbers and flushes underflows to zero rather
+ *	than implementing gradual underflow, then you must also #define
+ *	Sudden_Underflow.
+ * #define USE_LOCALE to use the current locale's decimal_point value.
+ * #define SET_INEXACT if IEEE arithmetic is being used and extra
+ *	computation should be done to set the inexact flag when the
+ *	result is inexact and avoid setting inexact when the result
+ *	is exact.  In this case, dtoa.c must be compiled in
+ *	an environment, perhaps provided by #include "dtoa.c" in a
+ *	suitable wrapper, that defines two functions,
+ *		int get_inexact(void);
+ *		void clear_inexact(void);
+ *	such that get_inexact() returns a nonzero value if the
+ *	inexact bit is already set, and clear_inexact() sets the
+ *	inexact bit to 0.  When SET_INEXACT is #defined, strtod
+ *	also does extra computations to set the underflow and overflow
+ *	flags when appropriate (i.e., when the result is tiny and
+ *	inexact or when it is a numeric value rounded to +-infinity).
+ * #define NO_ERRNO if strtod should not assign errno = ERANGE when
+ *	the result overflows to +-Infinity or underflows to 0.

+ * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 112-126].
+ *
+ * Modifications:
+ *	1. Rather than iterating, we use a simple numeric overestimate
+ *	   to determine k = floor(log10(d)).  We scale relevant
+ *	   quantities using O(log2(k)) rather than O(k) multiplications.
+ *	2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
+ *	   try to generate digits strictly left to right.  Instead, we
+ *	   compute with fewer bits and propagate the carry if necessary
+ *	   when rounding the final digit up.  This is often faster.
+ *	3. Under the assumption that input will be rounded nearest,
+ *	   mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
+ *	   That is, we allow equality in stopping tests when the
+ *	   round-nearest rule will give the same floating-point value
+ *	   as would satisfaction of the stopping test with strict
+ *	   inequality.
+ *	4. We remove common factors of powers of 2 from relevant
+ *	   quantities.
+ *	5. When converting floating-point integers less than 1e16,
+ *	   we use floating-point arithmetic rather than resorting
+ *	   to multiple-precision integers.
+ *	6. When asked to produce fewer than 15 digits, we first try
+ *	   to get by with floating-point arithmetic; we resort to
+ *	   multiple-precision integer arithmetic only if we cannot
+ *	   guarantee that the floating-point calculation has given
+ *	   the correctly rounded result.  For k requested digits and
+ *	   "uniformly" distributed input, the probability is
+ *	   something like 10^(k-15) that we must resort to the Long
+ *	   calculation.

+NSPR 2.0 evolution
+------------------
+
+
+Phase 1- today
+
+Currently (Oct 10, 1996) NSPR 2.0 has two modes.  Either _PR_NTHREAD 
+is defined, in which case the PR_CreateThread() call always creates a 
+native kernel thread, or _PR_NTHREAD is not defined and PR_CreateThread() 
+always creates user level threads within the single, original process.  This 
+source code is reflected in two directories, nspr20/pr/src/threads/native, and 
+nspr20/pr/src/threads/user.  Although the PR_CreateThread() function has
+a paramter to specify the "scope" of a thread, this parameter is not yet 
+used- except on solaris where it uses it to specify bound vs unbound threads.
+
+Phase 2 - next week
+
+The next step is to provide a combination of user and native threads.  The
+idea, of course, is to have some small number of native threads and each of 
+those threads be able to run user level threads.  The number of native
+threads created will most likely be proportional to the number of CPUs in
+the system.  For this reason, the specific set of native threads which are
+used to run the user-level threads will be called "CPU" threads.  
+
+The user level threads which will be run on the CPU threads are able to
+run on any of the CPU threads available, and over the course of a user-level
+thread's lifetime, it may drift from one CPU thread to another.  All 
+user-level threads will compete for processing time via a single run queue.
+
+Creation of a CPU thread will be primarily controlled by NSPR itself or by
+the user running a function PR_Concurrency().  The details of PR_Concurrency()
+have not yet been worked out; but the idea is that the user can specify to 
+NSPR how many CPU threads are desired.
+
+In this system, user-level threads are created by using PR_CreateThread() and
+specifying the PR_LOCAL_SCOPE option.  LOCAL_SCOPE indicates that the thread
+will be under the control of the "local" scheduler.  Creating threads with
+GLOBAL_SCOPE, on the other hand will create a thread which is under the 
+control of the system's scheduler.  In otherwords, this creates a native thread
+which is not a CPU thread; it runs a single thread task and never has more 
+than one task to run.  LOCAL_SCOPE is much like creating a Solaris unbound 
+thread, while GLOBAL_SCOPE is similar to creating a Solaris bound thread.
+
+To implement this architecture, the source code will still maintain the "user"
+and "native" directories which is has today.  However a third directory 
+"combined" will also exist.  To compile a version of NSPR which only creates
+native threads, the user can define _PR_NTHREAD.  For exclusive user-level
+threads, do not define _PR_NTHREAD.  To get the combined threads, define
+_PR_NTHREAD and _PR_USE_CPUS.
+
+
+Phase 3 - later than next week
+
+The goal is to eliminate the 3 directories.  Once these three models are in
+place, the remaining work will be to eliminate the native and user thread
+directories for all platforms, so that the entire thread model is contained
+within what is today called the "combined" model.  This new and glorious
+source code will attempt to make the "combined" model on any platforms which
+provide the necessary underlying native threading, but will also be 
+capable of using exclusive user-level threads on systems which don't have
+native threads.

+** There is a counter, initialized to zero and incremented every time a

+** called. The size of the vector will be some value greater than or equal
+** to the current high water mark. Each thread has its own TPD length and

+**
+** Name: accept.c
+**
+** Description: Run accept() sucessful connection tests.
+**
+** Modification History:
+** 04-Jun-97 AGarcia - Reconvert test file to return a 0 for PASS and a 1 for FAIL
+** 13-May-97 AGarcia- Converted the test to accomodate the debug_mode 
+**             The debug mode will print all of the printfs associated with this test.
+**             The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**             have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**            recognize the return code from tha main program.
+** 12-June-97 Revert to return code 0 and 1.

+**
+** Name: alarmtst.c
+**
+** Description: Test alarms
+**
+** Modification History:
+** 13-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+** File: anonfm.c
+** Description: Test anonymous file map 
+**
+** Synopsis: anonfm [options] [dirName]
+**
+** Options:
+** -d   enable debug mode
+** -h   display a help message
+** -s <n>  size of the anonymous memory map, in KBytes. default: 100KBytes.
+** -C 1 Operate this process as ClientOne() 
+** -C 2 Operate this process as ClientTwo()
+**
+** anonfn.c contains two tests, corresponding to the two protocols for
+** passing an anonymous file map to a child process.
+**
+** ServerOne()/ClientOne() tests the passing of "raw" file map; it uses
+** PR_CreateProcess() [for portability of the test case] to create the
+** child process, but does not use the PRProcessAttr structure for
+** passing the file map data.
+**
+** ServerTwo()/ClientTwo() tests the passing of the file map using the
+** PRProcessAttr structure.

+/***********************************************************************
+**  1996 - Netscape Communications Corporation
+**
+** Name: attach.c
+**
+** Description: Platform-specific code to create a native thread. The native thread will
+**                            repeatedly call PR_AttachThread and PR_DetachThread. The
+**                            primordial thread waits for this new thread to finish.
+**
+** Modification History:
+** 13-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.
+** 12-June-97 Revert to return code 0 and 1.

+ *
+ * Notes:
+ * [1] lth. The call to Sleep() is a hack to get the test case to run
+ * on Windows 95. Without it, the test case fails with an error
+ * WSAECONNRESET following a recv() call. The error is caused by the
+ * server side thread termination without a shutdown() or closesocket()
+ * call. Windows docmunentation suggests that this is predicted
+ * behavior; that other platforms get away with it is ... serindipity.
+ * The test case should shutdown() or closesocket() before
+ * thread termination. I didn't have time to figure out where or how
+ * to do it. The Sleep() call inserts enough delay to allow the
+ * client side to recv() all his data before the server side thread
+ * terminates. Whew! ...
+ *
+ ** Modification History:
+ * 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+ *             The debug mode will print all of the printfs associated with this test.
+ *             The regress mode will be the default mode. Since the regress tool limits
+ *           the output to a one line status:PASS or FAIL,all of the printf statements
+ *             have been handled with an if (debug_mode) statement.

+** Modification History:

+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.
+** 12-June-97 Revert to return code 0 and 1.

+** Description: Testing malloc (OBSOLETE)
+**
+** Modification History:
+** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.

+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to

+**
+** Name: fileio.c
+**
+** Description: Program to copy one file to another. 
+**
+** Modification History:
+** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.
+** 12-June-97 Revert to return code 0 and 1, remove debug option (obsolete).

+**
+** Name: forktest.c
+**
+** Description: UNIX test for fork functions.
+**
+** Modification History:
+** 15-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**                 The debug mode will print all of the printfs associated with this test.
+**                         The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**                         have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**                        recognize the return code from tha main program.
+** 12-June-97 AGarcic - Revert to return code 0 and 1, remove debug option (obsolete).

+** description:     Interval conversion test.
+** Modification History:
+** 15-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+** File:    instrumt.c
+** Description: This test is for the NSPR debug aids defined in
+** prcountr.h, prtrace.h, prolock.h
+**
+** The test case tests the three debug aids in NSPR:
+**
+** Diagnostic messages can be enabled using "instrumt -v 6"
+** This sets the msgLevel to something that PR_LOG() likes.
+** Also define in the environment "NSPR_LOG_MODULES=Test:6"
+**
+** CounterTest() tests the counter facility. This test
+** creates 4 threads. Each thread either increments, decrements,
+** adds to or subtracts from a counter, depending on an argument
+** passed to the thread at thread-create time. Each of these threads
+** does COUNT_LIMIT iterations doing its thing. When all 4 threads
+** are done, the result of the counter is evaluated. If all was atomic,
+** the the value of the counter should be zero.
+**
+** TraceTest():
+** This test mingles with the counter test. Counters trace.
+** A thread to extract trace entries on the fly is started.
+** A thread to dump trace entries to a file is started.

+** Test socket IO timeouts
+**
+**
+**
+**
+** Modification History:
+** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.

+** Description:Test socket IO timeouts (kernel level)
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+** Name: dbmalloc1.c

+** Description: Tests PR_SetMallocCountdown PR_ClearMallocCountdown functions.
+**
+** Modification History:
+** 
+** 19-May-97 AGarcia - separate the four join tests into different unit test modules.
+**		    AGarcia- Converted the test to accomodate the debug_mode flag.
+**          The debug mode will print all of the printfs associated with this test.
+**		    The regress mode will be the default mode. Since the regress tool limits
+**          the output to a one line status:PASS or FAIL,all of the printf statements
+**		    have been handled with an if (debug_mode) statement.

+** Description: Testing lazy initialization
+**
+**      Since you only get to initialize once, you have to rerun the test
+**      for each test case. The test cases are numbered. If you want to
+**      add more tests, take the next number and add it to the switch
+**      statement.
+**
+**      This test is problematic on systems that don't support the notion

+**      initializations themselves, which defeats the purpose here.

+** -v       verbose mode; displays progress in test, plus -d
+** -h       gives usage message.
+**
+** Description:
+** lltest.c tests the functions defined in NSPR 2.0's prlong.h.
+** 
+** Successive tests begin to depend on other LL functions working
+** correctly. So, ... Do not change the order of the tests as run

+** 
+** Caveats:
+** Do not even begin to think that this is an exhaustive test!
+**
+** These tests try a little of everything, but not all boundary
+** conditions and limits are tested.
+** You want better coverage? ... Add it.

+** File:        lock.c
+** Purpose:     test basic locking functions
+**
+** Modification History:
+** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.
+**
+** 11-Aug-97 LarryH. Win16 port of NSPR.
+**           - Added "PASS", "FAIL" messages on completion.
+**           - Change stack variables to static scope variables
+**             because of shadow-stack use by Win16
+**           - Added PR_CALLBACK attribute to functions called by NSPR
+**           - Added command line arguments:
+**             - l <num> to control the number of loops
+**             - c <num> to control the number of CPUs.
+**             (was positional argv).

+** File:        lockfile.c
+** Purpose:     test basic locking functions
+**              Just because this times stuff, don't think its a perforamnce
+**              test!!!
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+** File: mbcs.c
+**
+** Synopsis: mbcs {dirName}
+**
+** where dirName is the directory to be traversed. dirName is required.
+**
+** Description: 
+** mbcs.c tests use of multi-byte characters, as would be passed to
+** NSPR funtions by internationalized applications. 
+**
+** mbcs.c, when run on any single-byte platform, should run correctly.
+** In truth, running the mbcs test on a single-byte platform is
+** really meaningless. mbcs.c, nor any NSPR library or test is not
+** intended for use with any wide character set, including Unicode.
+** mbcs.c should not be included in runtests.ksh because it requires
+** extensive user intervention to set-up and run.
+**
+** mbcs.c should be run on a platform using some form of multi-byte
+** characters. The initial platform for this test is a Japanese
+** language Windows NT 4.0 machine. ... Thank you Noriko Hoshi.
+**
+** To run mbcs.c, the tester should create a directory tree containing
+** some files in the same directory from which the test is run; i.e.
+** the current working directory. The directory and files should be
+** named such that when represented in the local multi-byte character
+** set, one or more characters of the name is longer than a single
+** byte.

+** File: nameshm1.c -- Test Named Shared Memory
+**
+** Description: 
+** nameshm1 tests Named Shared Memory. nameshm1 performs two tests of
+** named shared memory. 
+** 
+** The first test is a basic test. The basic test operates as a single
+** process. The process exercises all the API elements of the facility.
+** This test also attempts to write to all locations in the shared
+** memory.
+**
+** The second test is a client-server test. The client-server test
+** creates a new instance of nameshm1, passing the -C argument to the
+** new process; this creates the client-side process. The server-side
+** (the instance of nameshm1 created from the command line) and the
+** client-side interact via inter-process semaphores to verify that the
+** shared memory segment can be read and written by both sides in a
+** synchronized maner.
+**
+** Note: Because this test runs in two processes, the log files created
+** by the test are not in chronological sequence; makes it hard to read.
+** As a temporary circumvention, I changed the definition(s) of the
+** _PUT_LOG() macro in prlog.c to force a flushall(), or equivalent.
+** This causes the log entries to be emitted in true chronological
+** order.
+**
+** Synopsis: nameshm1 [options] [name]
+** 
+** Options:
+** -d       Enables debug trace via PR_LOG()
+** -v       Enables verbose mode debug trace via PR_LOG()
+** -w       Causes the basic test to attempt to write to the segment
+**          mapped as read-only. When this option is specified, the
+**          test should crash with a seg-fault; this is a destructive
+**          test and is considered successful when it seg-faults.
+** 
+** -C       Causes nameshm1 to start as the client-side of a
+**          client-server pair of processes. Only the instance
+**          of nameshm1 operating as the server-side process should
+**          specify the -C option when creating the client-side process;
+**          the -C option should not be specified at the command line.
+**          The client-side uses the shared memory segment created by
+**          the server-side to communicate with the server-side
+**          process.
+**          
+** -p <n>   Specify the number of iterations the client-server tests
+**          should perform. Default: 1000.
+**
+** -s <n>   Size, in KBytes (1024), of the shared memory segment.
+**          Default: (10 * 1024)
+**
+** -i <n>   Number of client-side iterations. Default: 3
+**
+** name     specifies the name of the shared memory segment to be used.
+**          Default: /tmp/xxxNSPRshm
+**

+ * A test for nonblocking connect.  Functions tested include PR_Connect,
+ * PR_Poll, and PR_GetConnectStatus.
+ *
+ * The test should be invoked with a host name, for example:
+ *     nbconn www.netscape.com
+ * It will do a nonblocking connect to port 80 (HTTP) on that host,
+ * and when connected, issue the "GET /" HTTP command.
+ *
+ * You should run this test in three ways:
+ * 1. To a known web site, such as www.netscape.com.  The HTML of the
+ *    top-level page at the web site should be printed.
+ * 2. To a machine not running a web server at port 80.  This test should
+ *    fail.  Ideally the error code should be PR_CONNECT_REFUSED_ERROR.
+ *    But it is possible to return PR_UNKNOWN_ERROR on certain platforms.
+ * 3. To an unreachable machine, for example, a machine that is off line.
+ *    The test should fail after the connect times out.  Ideally the
+ *    error code should be PR_IO_TIMEOUT_ERROR, but it is possible to
+ *    return PR_UNKNOWN_ERROR on certain platforms.

+** File: ntioto.c
+** Description: 
+** This test, ntioto.c, was designed to reproduce a bug reported by NES
+** on WindowsNT (fibers implementation). NSPR was asserting in ntio.c
+** after PR_AcceptRead() had timed out. I/O performed subsequent to the
+** call to PR_AcceptRead() could complete on a CPU other than the one
+** on which it was started. The assert in ntio.c detected this, then
+** asserted.
+**
+** Design:
+** This test will fail with an assert in ntio.c if the problem it was
+** designed to catch occurs. It returns 0 otherwise.
+** 
+** The main() thread initializes and tears things down. A file is
+** opened for writing; this file will be written to by AcceptThread()
+** and JitterThread().  Main() creates a socket for reading, listens
+** and binds the socket.
+** 
+** ConnectThread() connects to the socket created by main, then polls
+** the "state" variable. When state is AllDone, ConnectThread() exits.
+**
+** AcceptThread() calls PR_AcceptRead() on the socket. He fully expects
+** it to time out. After the timeout, AccpetThread() interacts with
+** JitterThread() via a common condition variable and the state
+** variable. The two threads ping-pong back and forth, each thread
+** writes the the file opened by main. This should provoke the
+** condition reported by NES (if we didn't fix it).
+**
+** The failure is not solid. It may fail within a few ping-pongs between
+** AcceptThread() and JitterThread() or may take a while. The default
+** iteration count, jitter, is set by DEFAULT_JITTER. This may be
+** modified at the command line with the -j option.

+/***********************************************************************
+**
+** Name: prpoll_to.c
+**
+** Description: This program tests PR_Poll with sockets.
+**              Timeout operation is tested
+**
+** Modification History:
+** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+ * Notes:
+ * [1] lth. The call to Sleep() is a hack to get the test case to run
+ * on Windows 95. Without it, the test case fails with an error
+ * WSAECONNRESET following a recv() call. The error is caused by the
+ * server side thread termination without a shutdown() or closesocket()
+ * call. Windows docmunentation suggests that this is predicted
+ * behavior; that other platforms get away with it is ... serindipity.
+ * The test case should shutdown() or closesocket() before
+ * thread termination. I didn't have time to figure out where or how
+ * to do it. The Sleep() call inserts enough delay to allow the
+ * client side to recv() all his data before the server side thread
+ * terminates. Whew! ...
+ *
+ ** Modification History:
+ * 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+ *             The debug mode will print all of the printfs associated with this test.
+ *             The regress mode will be the default mode. Since the regress tool limits
+ *           the output to a one line status:PASS or FAIL,all of the printf statements
+ *             have been handled with an if (debug_mode) statement.

+** Name: prselect_err.c

+** Description: tests PR_Select with sockets Error condition functions.

+** Modification History:

+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.

+** Description: Test to hammer on various components of NSPR
+** Modification History:
+** 20-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+** Name: prselect_to.c
+**
+** Description: tests PR_Select with sockets. Time out functions
+**
+** Modification History:
+** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+** Name: sem.c
+**
+** Description: Tests Semaphonre functions.
+**
+** Modification History:
+** 20-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+**
+** This server simulates a server running in loopback mode.
+**
+** The idea is that a single server is created.  The server initially creates
+** a number of worker threads.  Then, with the server running, a number of 
+** clients are created which start requesting service from the server.
+**
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.

+/***********************************************************************
+**
+** This server simulates a server running in loopback mode.
+**
+** The idea is that a single server is created.  The server initially creates
+** a number of worker threads.  Then, with the server running, a number of 
+** clients are created which start requesting service from the server.
+**
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+/***********************************************************************
+**
+** This server simulates a server running in loopback mode.
+**
+** The idea is that a single server is created.  The server initially creates
+** a number of worker threads.  Then, with the server running, a number of 
+** clients are created which start requesting service from the server.
+**
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+/***********************************************************************
+**
+** This server simulates a server running in loopback mode.
+**
+** The idea is that a single server is created.  The server initially creates
+** a number of worker threads.  Then, with the server running, a number of 
+** clients are created which start requesting service from the server.
+**
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+/***********************************************************************
+**
+** This server simulates a server running in loopback mode.
+**
+** The idea is that a single server is created.  The server initially creates
+** a number of worker threads.  Then, with the server running, a number of 
+** clients are created which start requesting service from the server.
+**
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.
+** 04-June-97 AGarcia removed the Test_Result function. Regress tool has been updated to
+**			recognize the return code from tha main program.

+**
+** Name: tmocon.c
+**
+** Description: test client socket connection.
+**
+** Modification History:
+** 19-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+**	         The debug mode will print all of the printfs associated with this test.
+**			 The regress mode will be the default mode. Since the regress tool limits
+**           the output to a one line status:PASS or FAIL,all of the printf statements
+**			 have been handled with an if (debug_mode) statement.

+/*******************************************************************
+** udpsrc.c -- Test basic function of UDP server
+**
+** udpsrv operates on the same machine with program udpclt.
+** udpsrv is the server side of a udp sockets application.
+** udpclt is the client side of a udp sockets application.
+**
+** The test is designed to assist developers in porting/debugging
+** the UDP socket functions of NSPR.
+**
+** This test is not a stress test.
+**
+** main() starts two threads: UDP_Server() and UDP_Client();
+** main() uses PR_JoinThread() to wait for the threads to complete.
+**
+** UDP_Server() does repeated recvfrom()s from a socket.
+** He detects an EOF condition set by UDP_Client(). For each
+** packet received by UDP_Server(), he checks its content for
+** expected content, then sends the packet back to UDP_Client().
+** 
+** UDP_Client() sends packets to UDP_Server() using sendto()
+** he recieves packets back from the server via recvfrom().
+** After he sends enough packets containing UDP_AMOUNT_TO_WRITE
+** bytes of data, he sends an EOF message.
+** 
+** The test issues a pass/fail message at end.
+** 
+** Notes:
+** The variable "_debug_on" can be set to 1 to cause diagnostic
+** messages related to client/server synchronization. Useful when
+** the test hangs.
+** 
+** Error messages are written to stdout.

+ * TEST 1: TestExplodeImplodeTime
+ * Description:
+ * For each given timestamp T (a PRTime value), call PR_ExplodeTime
+ * with GMT, US Pacific, and local time parameters.  Compare the
+ * resulting calendar (exploded) time values with the expected
+ * values.
+ *
+ * Note: the expected local time values depend on the local time
+ * zone.  The local time values stored in this test are for the US
+ * Pacific Time Zone.  If you are running this test in a different
+ * time zone, you need to modify the values in the localt array.
+ * An example is provided below.
+ *
+ * Call PR_ImplodeTime for each of the exploded values and compare
+ * the resulting PRTime values with the original input.
+ * 
+ * This test is run for the values of time T corresponding to the
+ * following dates:
+ * - 12/31/99 - before 2000 
+ * - 01/01/00 - after 2000 
+ * - Leap year - Feb 29, 2000 
+ * - March 1st, 2001 (after 1 year) 
+ * - March 1st, 2005 (after second leap year) 
+ * - 09/09/99 (used by some programs as an end of file marker)
+ *
+ * Call PR_Now, convert to calendar time using PR_ExplodeTime and
+ * manually check the result for correctness. The time should match
+ * the system clock.
+ *
+ * Tested functions: PR_Now, PR_ExplodeTime, PR_ImplodeTime,
+ * PR_LocalTimeParameters, PR_GMTParameters.

+ * Test: y2ktmo
+ *
+ * Description:
+ *   This test tests the interval time facilities in NSPR for Y2K
+ *   compliance.  All the functions that take a timeout argument
+ *   are tested: PR_Sleep, socket I/O (PR_Accept is taken as a
+ *   representative), PR_Poll, PR_WaitCondVar, PR_Wait, and
+ *   PR_CWait.  A thread of each thread scope (local, global, and
+ *   global bound) is created to call each of these functions.
+ *   The test should be started at the specified number of seconds
+ *   (called the lead time) before a Y2K rollover test date.  The
+ *   timeout values for these threads will span over the rollover
+ *   date by at least the specified number of seconds.  For
+ *   example, if the lead time is 5 seconds, the test should
+ *   be started at time (D - 5), where D is a rollover date, and
+ *   the threads will time out at or after time (D + 5).  The
+ *   timeout values for the threads are spaced one second apart.
+ *
+ *   When a thread times out, it calls PR_IntervalNow() to verify
+ *   that it did wait for the specified time.  In addition, it
+ *   calls a platform-native function to verify the actual elapsed
+ *   time again, to rule out the possibility that PR_IntervalNow()
+ *   is broken.  We allow the actual elapsed time to deviate from
+ *   the specified timeout by a certain tolerance (in milliseconds).

+ * Test: zerolen.c 
+ *
+ * Description: a test for Bugzilla bug #17699.  We perform
+ * the same test for PR_Writev, PR_Write, and PR_Send.  In
+ * each test the server thread first fills up the connection
+ * to the client so that the next write operation will fail
+ * with EAGAIN.  Then it calls PR_Writev, PR_Write, or PR_Send
+ * with a zero-length buffer.  The client thread initially
+ * does not read so that the connection can be filled up.
+ * Then it empties the connection so that the server thread's
+ * PR_Writev, PR_Write, or PR_Send call can succeed.
+ *
+ * Bug #17699 is specific to the pthreads version on Unix,
+ * so on other platforms this test does nothing.
