| <para><function>chroot</function> only emulates a chroot function call |
| by keeping track of the current root and accomodating this in the file |
| related function calls. A real chroot functionality is not supported by |
| Windows however.</para> |
| |
| <para><function>clock_nanosleep</function> currently supports only |
| CLOCK_REALTIME and CLOCK_MONOTONIC. <function>clock_setres</function>, |
| <function>clock_settime</function>, and <function>timer_create</function> |
| currently support only CLOCK_REALTIME.</para> |
| |
| <para>POSIX file locks via <function>fcntl</function> or |
| <function>lockf</function>, as well as BSD <function>flock</function> locks |
| are advisory locks. They don't interact with Windows mandatory locks, nor |
| do POSIX fcntl locks interfere with BSD flock locks or vice versa.</para> |
| |
| <para>BSD file locks created via <function>flock</function> are only |
| propagated to the direct parent process, not to grand parents or sibling |
| processes. The locks are only valid in the creating process, its parent |
| process, and subsequently started child processes sharing the same file |
| descriptor.</para> |
| |
| <para>In very rare circumstances an application would want to use Windows |
| mandatory locks to interact with non-Cygwin Windows processes accessing the |
| same file (databases, etc). For these purposes, the entire locking mechanism |
| (fcntl/flock/lockf) can be switched to Windows mandatory locks on a |
| per-descriptor/per-process basis. For this purpose, use the call |
| |
| <screen> |
| fcntl (fd, F_LCK_MANDATORY, 1); |
| </screen> |
| |
| After that, all file locks on this descriptor will follow Windows mandatory |
| record locking semantics: Locks are per-descriptor/per-process; locks are not |
| propagated to child processes, not even via <function>execve</function>; |
| no atomic replacement of read locks with write locks and vice versa on the |
| same descriptor; locks have to be unlocked exactly as they have been locked. |
| </para> |
| |
| <para><function>fpclassify</function>, <function>isfinite</function>, |
| <function>isgreater</function>, <function>isgreaterequal</function>, |

| <function>islessequal</function>, <function>islessgreater</function>, |
| <function>isnan</function>, <function>isnormal</function>, |
| <function>isunordered</function>, and <function>signbit</function> |
| only support float and double arguments, not long double arguments.</para> |
| |
| <para><function>getitimer</function> and <function>setitimer</function> |
| only support ITIMER_REAL for now.</para> |
| |
| <para><function>link</function> will fail on FAT, FAT32, and other filesystems |
| not supporting hardlinks, just as on Linux.</para> |
| |
| <para><function>lseek</function> only works properly on files opened in |
| binary mode. On files opened in textmode (via mount mode or explicit |
| open flag) its positioning is potentially unreliable.</para> |
| |
| <para><function>setuid</function> is only safe against reverting the user |
| switch after a call to one of the exec(2) functions took place. Windows |
| doesn't support a non-revertable user switch within the context of Win32 |
| processes.</para> |
| |
| <para><function>vfork</function> just calls <function>fork</function>.</para> |
| |
| <para><function>vhangup</function> and <function>revoke</function> always |
| return -1 and set errno to ENOSYS. <function>grantpt</function> and |
| <function>unlockpt</function> always just return 0.</para> |
| |
| <para>The XSI IPC functions <function>semctl</function>, |
| <function>semget</function>, <function>semop</function>, |
| <function>shmat</function>, <function>shmctl</function>, |
| <function>shmdt</function>, <function>shmget</function>, |
| <function>msgctl</function>, <function>msgget</function>, |
| <function>msgrcv</function> and <function>msgsnd</function> are only |
| available when cygserver is running.</para> |
| |
| <para>The Linux-specific function <function>quotactl</function> only implements |
| what works on Windows: Windows only supports user block quotas on NTFS, no |
| group quotas, no inode quotas, no time constraints.</para> |
| |
| <para><function>qsort_r</function> is available in both BSD and GNU flavors, |
| depending on whether _BSD_SOURCE or _GNU_SOURCE is defined when compiling.</para> |
| |
| <para>The Linux-specific function <function>renameat2</function> only |
| supports the RENAME_NOREPLACE flag.</para> |
| |
| <para><function>basename</function> is available in both POSIX and GNU flavors, |
| depending on whether libgen.h is included or not.</para> |
| |
| <para><function>sigpause</function> is available in both BSD and SysV/XSI |
| flavors, depending on whether _XOPEN_SOURCE is defined when compiling.</para> |
| |
| <para><function>strerror_r</function> is available in both POSIX and GNU |
| flavors, depending on whether _GNU_SOURCE is defined when compiling.</para> |
| |
| <para><function>dladdr</function> always sets the Dl_info members dli_sname and |
| dli_saddr to NULL, indicating no symbol matching addr could be found.</para> |
