NAME

       stdbool.h - boolean type and values

SYNOPSIS

       #include <stdbool.h>

DESCRIPTION

       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       feature and may be withdrawn in a future version.

SEE ALSO

       None.
