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 The ability to undefine and redefine the macros bool, true, and false is an obsolescent feature that may be withdrawn in a future version of a standard.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. NetBSD 9.99 March 21, 2010 NetBSD 9.99
