    NAME

    assert.h - verify program assertion
 

    SYNOPSIS

    #include <assert.h>  

    DESCRIPTION

    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 IEEE Std 1003.1-2001 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.  

    APPLICATION USAGE
