    86 * This file should be included as
    87 *        #include <KHR/khrplatform.h>
    88 * by Khronos client API header files that use its types and defines.
    89 *
    90 * The types in khrplatform.h should only be used to define API-specific types.
    91 *
    92 * Types defined in khrplatform.h:
    93 *    khronos_int8_t              signed   8  bit
    94 *    khronos_uint8_t             unsigned 8  bit
    95 *    khronos_int16_t             signed   16 bit
    96 *    khronos_uint16_t            unsigned 16 bit
    97 *    khronos_int32_t             signed   32 bit
    98 *    khronos_uint32_t            unsigned 32 bit
    99 *    khronos_int64_t             signed   64 bit
   100 *    khronos_uint64_t            unsigned 64 bit
   101 *    khronos_intptr_t            signed   same number of bits as a pointer
   102 *    khronos_uintptr_t           unsigned same number of bits as a pointer
   103 *    khronos_ssize_t             signed   size
   104 *    khronos_usize_t             unsigned size
   105 *    khronos_float_t             signed   32 bit floating point
   106 *    khronos_time_ns_t           unsigned 64 bit time in nanoseconds
   107 *    khronos_utime_nanoseconds_t unsigned time interval or absolute time in
   108 *                                         nanoseconds
   109 *    khronos_stime_nanoseconds_t signed time interval in nanoseconds
   110 *    khronos_boolean_enum_t      enumerated boolean type. This should
   111 *      only be used as a base type when a client API's boolean type is
   112 *      an enum. Client APIs which use an integer or other type for
   113 *      booleans cannot use this as the base type for their boolean.
   114 *
   115 * Tokens defined in khrplatform.h:
   116 *
   117 *    KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
   118 *
   119 *    KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
   120 *    KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
   121 *
   122 * Calling convention macros defined in this file:
   123 *    KHRONOS_APICALL
   124 *    KHRONOS_APIENTRY
   125 *    KHRONOS_APIATTRIBUTES
   126 *
   127 * These may be used in function prototypes as:
   128 *
   129 *      KHRONOS_APICALL void KHRONOS_APIENTRY funcname(
