PROLOG         top

       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         top

       stdbool.h — boolean type and values

SYNOPSIS         top

       #include <stdbool.h>

DESCRIPTION         top

       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         top

       None.

RATIONALE         top

       None.

FUTURE DIRECTIONS         top

       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         top

       None.
