NAME
     stdbool -- standard boolean types

SYNOPSIS
     #include <stdbool.h>

DESCRIPTION
     The <stdbool.h> header defines four macros:

	 1.   bool, which expands to _Bool;

	 2.   true, which expands to the integer constant 1;

	 3.   false, which expands to the integer constant 0; and

	 4.   __bool_true_false_are_defined, which expands to the constant 1.

     The ability to undefine and redefine the macros bool, true, and false is an obsolescent feature that may be withdrawn in a future version of
     a standard.

SEE ALSO
     stdint(3)

STANDARDS
     The <stdbool.h> header conforms to ISO/IEC 9899:1999 (``ISO C99'') and IEEE Std 1003.1-2001 (``POSIX.1'').

HISTORY
     The <stdbool.h> header was first introduced in NetBSD 1.6.
