* of <inttypes.h> as proposed in the ISO/JTC1/SC22/WG14 C committee's working
* Programming language - C.
*
* types defined in this file should be through the inclusion of one of the
* following files:
*
* <sys/inttypes.h> Provides the Kernel and Driver appropriate
* components of <inttypes.h>.
*
* <inttypes.h> For use by applications.
*
* See these files for more details.

* Use at your own risk. This file will track the evolution of the revision
* of the current ISO C standard. As of February 1996, the committee is
* squarely behind the fixed sized types.

/*
* Constants
*
* The following macros create constants of the types defined in
* <sys/int_types.h>. The intent is that:
* Constants defined using these macros have a specific size and
* signedness. The suffix used for int64_t and uint64_t (ll and ull)
* are for examples only. Implementations are permitted to use other
* suffixes.
*
* The "CSTYLED" comments are flags to an internal code style analysis tool
* telling it to silently accept the line which follows. This internal
* standard requires a space between arguments, but the historical,
* non-ANSI-C ``method'' of concatenation can't tolerate those spaces.
