assert.h(0P) POSIX Programmer's Manual assert.h(0P)
This manual page is part of the POSIX Programmer's Manual. The Linux
implementation of this interface may differ (consult the
corresponding Linux manual page for details of Linux behavior), or
the interface may not be implemented on Linux.
assert.h — verify program assertion
#include <assert.h>
The functionality described on this reference page is aligned with
the ISO C standard. Any conflict between the requirements described
here and the ISO C standard is unintentional. This volume of
POSIX.1‐2008 defers to the ISO C standard.
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.
