assert.h: verify program assertion

NAME

assert.h - verify program assertion

SYNOPSIS

#include <assert.h>

DESCRIPTION

The <assert.h> header shall define the assert() 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() macro shall be defined simply as: #define assert(ignore)((void) 0) Otherwise, the macro behaves as described in assert(). The assert() macro shall be redefined according to the current state of NDEBUG each time <assert.h> is included. The assert() macro shall be implemented as a macro, not as a function. If the macro definition is suppressed in order to access an actual function, the behavior is undefined. The following sections are informative.

APPLICATION USAGE

None.
RATIONALE
None.
FUTURE DIRECTIONS
None.
