/*
 * This file, <sys/int_types.h>, is part of the Sun Microsystems implementation
 * of <inttypes.h> as proposed in the ISO/JTC1/SC22/WG14 C committee's working
 * draft for the revision of the current ISO C standard, ISO/IEC 9899:1990
 * Programming language - C.
 *
 * Programs/Modules should not directly include this file.  Access to the
 * types defined in this file should be through the inclusion of one of the
 * following files:
 *
 *	<sys/types.h>		Provides only the "_t" types defined in this
 *				file which is a subset of the contents of
 *				<inttypes.h>.  (This can be appropriate for
 *				all programs/modules except those claiming
 *				ANSI-C conformance.)
 *
 *	<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.  As of February 1996, the committee is squarely
 * behind the fixed sized types; the "least" and "fast" types are still being
 * discussed.  The probability that the "fast" types may be removed before
 * the standard is finalized is high enough that they are not currently
 * implemented.  The unimplemented "fast" types are of the form
 * [u]int_fast[0-9]*_t and [u]intfast_t.

 * Basic / Extended integer types

 * Implementations are free to typedef them to Standard C integer types or
 * extensions that they support. If an implementation does not support one
 * of the particular integer data types below, then it should not define the
 * typedefs and macros corresponding to that data type.  Note that int8_t
 * is not defined in -Xs mode on ISAs for which the ABI specifies "char"
 * as an unsigned entity because there is not way to defined an eight bit
 * signed integral.
