[Added with
C99]
Include the standard header <stdbool.h>
to define a type and several macros suitable for writing Boolean tests.
The standard header <stdbool.h>
is available even in a
freestanding implementation.
/* MACROS */
#define bool _Bool [keyword in C++]
#define false 0 [keyword in C++]
#define true 1 [keyword in C++]
#define __bool_true_false_are_defined 1
/* TYPES */
typedef i-type bool; [keyword in C++]
#define __bool_true_false_are_defined 1
The macro yields the decimal constant 1
.
#define bool _Bool [keyword in C++]
The macro yields the type _Bool.
#define false 0 [keyword in C++]
The macro yields the decimal constant 0
.
#define true 1 [keyword in C++]
The macro yields the decimal constant 1
.
