+/* Khronos platform-specific types and definitions.
+ *
+ * The master copy of khrplatform.h is maintained in the Khronos EGL
+ * Registry repository at https://github.com/KhronosGroup/EGL-Registry
+ * The last semantic modification to khrplatform.h was at commit ID:
+ * 67a3e0864c2d75ea5287b9f3d2eb74a745936692
+ *
+ * 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 filing pull requests or issues on
+ * the EGL Registry repository linked above.
+ *
+ *
+ * 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:
