- * 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;
