- * stdendian.h
- *
- * This header defines the following endian macros as defined here:
- * http://austingroupbugs.net/view.php?id=162
- *
- * BYTE_ORDER this macro shall have a value equal to one
- * of the *_ENDIAN macros in this header.
- * LITTLE_ENDIAN if BYTE_ORDER == LITTLE_ENDIAN, the host
- * byte order is from least significant to
- * most significant.
- * BIG_ENDIAN if BYTE_ORDER == BIG_ENDIAN, the host byte
- * order is from most significant to least
- * significant.
- *
- * The following are defined as macros:
- *
- * uint16_t bswap16(uint16_t x);
- * uint32_t bswap32(uint32_t x);
- * uint64_t bswap64(uint64_t x);
-
- * uint16_t htobe16(uint16_t x);
- * uint16_t htole16(uint16_t x);
- * uint16_t be16toh(uint16_t x);
- * uint16_t le16toh(uint16_t x);
- *
- * uint32_t htobe32(uint32_t x);
- * uint32_t htole32(uint32_t x);
- * uint32_t be32toh(uint32_t x);
- * uint32_t le32toh(uint32_t x);
- *
- * uint64_t htobe64(uint64_t x);
- * uint64_t htole64(uint64_t x);
- * uint64_t be64toh(uint64_t x);
- * uint64_t le64toh(uint64_t x);
- *
- * The header defines the following macro for OpenCL compatibility
- *
- https://www.khronos.org/registry/cl/sdk/2.0/docs/man/xhtml/preprocessorDirectives.html
- *
- * __ENDIAN_LITTLE__ if BYTE_ORDER == LITTLE_ENDIAN then this
- * macro is present for OpenCL compatibility
- *
- * The implementation provides a uniform interface to endian macros using only
- * system headers on recent Linux, Darwin, FreeBSD, Solaris and Windows
- systems.
- *
- * This approach is intended to avoid the need for preflight configure
- scripts.
- * An alternative approach would be to test compiler CPU architecture marcros.
- *
- * This header has had *limited* testing on recent C11/C++11 compilers and is
- * based on the austin bug tracker interface, manpages, and headers present in
- * Linux, FreeBSD, Windows, Solaris and Darwin.
- *
- * The header uses __builtin_bswapXX intrinsic with GCC/Clang (__GNUC__) on
- * platforms that do not provide bswap16, bswap32, bswap64 (Darwin)
- *
- * Public Domain.
