include/msgpack/predef/make.h  view on Meta::CPAN

These set of macros decompose common vendor version number
macros which are composed version, revision, and patch digits.
The naming convention indicates:

* The base of the specified version number. "`MSGPACK_PREDEF_MAKE_0X`" for
  hexadecimal digits, and "`MSGPACK_PREDEF_MAKE_10`" for decimal digits.
* The format of the vendor version number. Where "`V`" indicates the version digits,
  "`R`" indicates the revision digits, "`P`" indicates the patch digits, and "`0`"
  indicates an ignored digit.

Macros are:

include/msgpack/predef/other/endian.h  view on Meta::CPAN

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.
