NAME

       assert.h, assert - verify program assertion

SYNOPSIS

       #include <assert.h>

DESCRIPTION

       The <assert.h> header defines 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 is defined simply as:

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

       Otherwise, the macro behaves as described in assert(3C).

       The assert() macro is redefined according to the current state of NDEBUG each time <assert.h> is included.

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

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.
