| 31 * Adopters may modify this file to suit their platform. Adopters are | |
| 32 * encouraged to submit platform specific modifications to the Khronos | |
| 33 * group so that they can be included in future versions of this file. | |
| 34 * Please submit changes by sending them to the public Khronos Bugzilla | |
| 35 * (http://khronos.org/bugzilla) by filing a bug against product | |
| 36 * "Khronos (general)" component "Registry". | |
| 37 * | |
| 38 * A predefined template which fills in some of the bug fields can be | |
| 39 * reached using http://tinyurl.com/khrplatform-h-bugreport, but you | |
| 40 * must create a Bugzilla login first. | |

| 43 * See the Implementer's Guidelines for information about where this file | |
| 44 * should be located on your system and for more details of its use: | |
| 45 * http://www.khronos.org/registry/implementers_guide.pdf | |
| 46 * | |
| 47 * This file should be included as | |
| 48 * #include <KHR/khrplatform.h> | |
| 49 * by Khronos client API header files that use its types and defines. | |
| 50 * | |
| 51 * The types in khrplatform.h should only be used to define API-specific types. | |
| 52 * | |
| 53 * Types defined in khrplatform.h: | |
| 54 * khronos_int8_t signed 8 bit | |
| 55 * khronos_uint8_t unsigned 8 bit | |
| 56 * khronos_int16_t signed 16 bit | |
| 57 * khronos_uint16_t unsigned 16 bit | |
| 58 * khronos_int32_t signed 32 bit | |
| 59 * khronos_uint32_t unsigned 32 bit | |
| 60 * khronos_int64_t signed 64 bit | |
| 61 * khronos_uint64_t unsigned 64 bit | |
| 62 * khronos_intptr_t signed same number of bits as a pointer | |
| 63 * khronos_uintptr_t unsigned same number of bits as a pointer | |
| 64 * khronos_ssize_t signed size | |
| 65 * khronos_usize_t unsigned size | |
| 66 * khronos_float_t signed 32 bit floating point | |
| 67 * khronos_time_ns_t unsigned 64 bit time in nanoseconds | |
| 68 * khronos_utime_nanoseconds_t unsigned time interval or absolute time in | |
| 69 * nanoseconds | |
| 70 * khronos_stime_nanoseconds_t signed time interval in nanoseconds | |
| 71 * khronos_boolean_enum_t enumerated boolean type. This should | |
| 72 * only be used as a base type when a client API's boolean type is | |
| 73 * an enum. Client APIs which use an integer or other type for | |
| 74 * booleans cannot use this as the base type for their boolean. | |
| 75 * | |
| 76 * Tokens defined in khrplatform.h: | |
| 77 * | |
| 78 * KHRONOS_FALSE, KHRONOS_TRUE Enumerated boolean false/true values. | |
| 79 * | |
| 80 * KHRONOS_SUPPORT_INT64 is 1 if 64 bit integers are supported; otherwise 0. | |
| 81 * KHRONOS_SUPPORT_FLOAT is 1 if floats are supported; otherwise 0. | |
| 82 * | |
| 83 * Calling convention macros defined in this file: | |
| 84 * KHRONOS_APICALL | |
| 85 * KHRONOS_APIENTRY | |
| 86 * KHRONOS_APIATTRIBUTES | |
| 87 * | |
| 88 * These may be used in function prototypes as: | |
| 89 * | |
| 90 * KHRONOS_APICALL void KHRONOS_APIENTRY funcname( | |
| 91 * int arg1, | |
| 92 * int arg2) KHRONOS_APIATTRIBUTES; | |
