STDBOOL(3) BSD Library Functions Manual STDBOOL(3)NAMEstdbool — 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an obsolescent feature that may be withdrawn in a future version of a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 ALSOstdint(3)STANDARDS
The <stdbool.h> header conforms to ISO/IEC 9899:1999 (“ISO C99”) and IEEE
Std 1003.1-2001 (“POSIX.1”).
