NAME

       stdbool.h, stdbool - boolean type and values

SYNOPSIS

       #include <stdbool.h>

DESCRIPTION

       The <stdbool.h> header defines 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 can undefine and then possibly redefine the macros bool, true, and false.
