There are four defined macros in this header that define the various generally possible endian memory orderings: * `BOOST_ENDIAN_BIG_BYTE`, byte-swapped big-endian. * `BOOST_ENDIAN_BIG_WORD`, word-swapped big-endian. * `BOOST_ENDIAN_LITTLE_BYTE`, byte-swapped little-endian. * `BOOST_ENDIAN_LITTLE_WORD`, word-swapped little-endian. The detection is conservative in that it only identifies endianness that it knows for certain. In particular bi-endianness is not indicated as is it not practically possible to determine the endianness from anything but an operating system provided header. And the currently known headers do not define that programatic bi-endianness is available. This implementation is a compilation of various publicly available information and acquired knowledge: . The indispensable documentation of "Pre-defined Compiler Macros" http://sourceforge.net/p/predef/wiki/Endianness[Endianness]. . The various endian specifications available in the http://wikipedia.org/[Wikipedia] computer architecture pages. . Generally available searches for headers that define endianness. */ // end::reference[] #define BOOST_ENDIAN_BIG_BYTE BOOST_VERSION_NUMBER_NOT_AVAILABLE #define BOOST_ENDIAN_BIG_WORD BOOST_VERSION_NUMBER_NOT_AVAILABLE #define BOOST_ENDIAN_LITTLE_BYTE BOOST_VERSION_NUMBER_NOT_AVAILABLE #define BOOST_ENDIAN_LITTLE_WORD BOOST_VERSION_NUMBER_NOT_AVAILABLE /* GNU libc provides a header defining __BYTE_ORDER, or _BYTE_ORDER. * And some OSs provide some for of endian header also. */ #if !BOOST_ENDIAN_BIG_BYTE && !BOOST_ENDIAN_BIG_WORD && \ !BOOST_ENDIAN_LITTLE_BYTE && !BOOST_ENDIAN_LITTLE_WORD #
