1.34 + * Adopters may modify this file to suit their platform. Adopters are
1.35 + * encouraged to submit platform specific modifications to the Khronos
1.36 + * group so that they can be included in future versions of this file.
1.37 + * Please submit changes by sending them to the public Khronos Bugzilla
1.38 + * (http://khronos.org/bugzilla) by filing a bug against product
1.39 + * "Khronos (general)" component "Registry".
1.40 + *
1.41 + * A predefined template which fills in some of the bug fields can be
1.42 + * reached using http://tinyurl.com/khrplatform-h-bugreport, but you
1.43 + * must create a Bugzilla login first.
1.44 + *
1.45 + *
1.46 + * See the Implementer's Guidelines for information about where this file
1.47 + * should be located on your system and for more details of its use:
1.48 + * http://www.khronos.org/registry/implementers_guide.pdf
1.49 + *
1.50 + * This file should be included as
1.51 + * #include <KHR/khrplatform.h>
1.52 + * by Khronos client API header files that use its types and defines.
1.53 + *
1.54 + * The types in khrplatform.h should only be used to define API-specific types.
1.55 + *
1.56 + * Types defined in khrplatform.h:
1.57 + * khronos_int8_t signed 8 bit
1.58 + * khronos_uint8_t unsigned 8 bit
1.59 + * khronos_int16_t signed 16 bit
1.60 + * khronos_uint16_t unsigned 16 bit
1.61 + * khronos_int32_t signed 32 bit
1.62 + * khronos_uint32_t unsigned 32 bit
1.63 + * khronos_int64_t signed 64 bit
1.64 + * khronos_uint64_t unsigned 64 bit
1.65 + * khronos_intptr_t signed same number of bits as a pointer
1.66 + * khronos_uintptr_t unsigned same number of bits as a pointer
1.67 + * khronos_ssize_t signed size
1.68 + * khronos_usize_t unsigned size
1.69 + * khronos_float_t signed 32 bit floating point
1.70 + * khronos_time_ns_t unsigned 64 bit time in nanoseconds
1.71 + * khronos_utime_nanoseconds_t unsigned time interval or absolute time in
1.72 + * nanoseconds
1.73 + * khronos_stime_nanoseconds_t signed time interval in nanoseconds
1.74 + * khronos_boolean_enum_t enumerated boolean type. This should
1.75 + * only be used as a base type when a client API's boolean type is
1.76 + * an enum. Client APIs which use an integer or other type for
1.77 + * booleans cannot use this as the base type for their boolean.
1.78 + *
1.79 + * Tokens defined in khrplatform.h:
1.80 + *
1.81 + * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values.
1.82 + *
1.83 + * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0.
1.84 + * KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0.
1.85 + *
1.86 + * Calling convention macros defined in this file:
1.87 + * KHRONOS_APICALL
1.88 + * KHRONOS_APIENTRY
1.89 + * KHRONOS_APIATTRIBUTES
1.90 + *
