PROLOG
This manual page is part of the POSIX Programmer's Manual.
The Linux implementation of this interface may differ (consult
the corresponding Linux manual page for details of Linux behavior),
or the interface may not be implemented on Linux.
NAME
stdbool.h
--- boolean type and values
SYNOPSIS
#include <stdbool.h>
DESCRIPTION
The functionality described on this reference page is aligned with the
ISO C standard. Any conflict between the requirements described here and the
ISO C standard is unintentional. This volume of POSIX.1-2008 defers to the ISO C standard.
The
<stdbool.h>
header shall define the following macros:
- bool
-
Expands to
_Bool.
- true
-
Expands to the integer constant 1.
- false
-
Expands to the integer constant 0.
- __bool_true_false_are_defined
-
Expands to the integer constant 1.
An application may undefine and then possibly redefine the macros bool,
true, and false.
The following sections are informative.
APPLICATION USAGE
None.
RATIONALE
None.
FUTURE DIRECTIONS
The ability to undefine and redefine the macros bool, true, and false
is an obsolescent feature and may be removed in a future version.
SEE ALSO
None.
