  * Please submit changes by sending them to the public Khronos Bugzilla
  * (http://khronos.org/bugzilla) by filing a bug against product

  * 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_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:
