| * |
| * Adopters may modify this file to suit their platform. Adopters are |
| * encouraged to submit platform specific modifications to the Khronos |
| * group so that they can be included in future versions of this file. |
| * Please submit changes by sending them to the public Khronos Bugzilla |
| * (http://khronos.org/bugzilla) by filing a bug against product |
| * "Khronos (general)" component "Registry". |
| * |
| * A predefined template which fills in some of the bug fields can be |
| * reached using http://tinyurl.com/khrplatform-h-bugreport, but you |
| * must create a Bugzilla login first. |
| * |
| * |
| * See the Implementer's Guidelines for information about where this file |
| * should be located on your system and for more details of its use: |
| * http://www.khronos.org/registry/implementers_guide.pdf |
| * |
| * This file should be included as |
| * #include <KHR/khrplatform.h> |
| * by Khronos client API header files that use its types and defines. |
| * |
| * The types in khrplatform.h should only be used to define API-specific types. |
| * |
| * Types defined in khrplatform.h: |
| * khronos_int8_t signed 8 bit |
| * khronos_uint8_t unsigned 8 bit |
| * khronos_int16_t signed 16 bit |
| * khronos_uint16_t unsigned 16 bit |
| * khronos_int32_t signed 32 bit |
| * khronos_uint32_t unsigned 32 bit |
| * khronos_int64_t signed 64 bit |
| * khronos_uint64_t unsigned 64 bit |
| * khronos_intptr_t signed same number of bits as a pointer |
| * khronos_uintptr_t unsigned same number of bits as a pointer |
| * khronos_ssize_t signed size |
| * khronos_usize_t unsigned size |
| * khronos_float_t signed 32 bit floating point |
| * khronos_time_ns_t unsigned 64 bit time in nanoseconds |
| * khronos_utime_nanoseconds_t unsigned time interval or absolute time in |
| * nanoseconds |
| * khronos_stime_nanoseconds_t signed time interval in nanoseconds |
| * khronos_boolean_enum_t enumerated boolean type. This should |
| * only be used as a base type when a client API's boolean type is |
| * an enum. Client APIs which use an integer or other type for |
| * booleans cannot use this as the base type for their boolean. |
| * |
| * Tokens defined in khrplatform.h: |
| * |
| * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values. |
| * |
| * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0. |
| * KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0. |
| * |
| * Calling convention macros defined in this file: |
| * KHRONOS_APICALL |
| * KHRONOS_APIENTRY |
| * KHRONOS_APIATTRIBUTES |
| * |
| * These may be used in function prototypes as: |
| * |
| * KHRONOS_APICALL void KHRONOS_APIENTRY funcname( |
| * int arg1, |
| * int arg2) KHRONOS_APIATTRIBUTES; |
