NAME

assert.h — verify program assertion

SYNOPSIS

#include <assert.h>

DESCRIPTION

The <assert.h> header defines the assert(3) macro. It refers to the macro NDEBUG which is not defined in the header. If NDEBUG is defined as a macro name before the inclusion of this header, the assert(3) macro is defined simply as:

#define assert(ignore)((void) 0)

otherwise the macro behaves as described in assert().

The assert() macro is implemented as a macro, not as a function. If the macro definition is suppressed in order to access an actual function, the behaviour is undefined.

APPLICATION USAGE

None.

FUTURE DIRECTIONS

None.
