ASSERT(3)           Linux Programmer's Manual           ASSERT(3)
NAME
       assert - Abort the program if assertion is false.
SYNOPSIS
       #include <assert.h>
       void assert (int expression);
DESCRIPTION
       assert()  prints  an  error message to standard output and
       terminates the program by calling abort() if expression is
       false  (i.e.,  compares equal to zero).  This only happens
       when the macro NDEBUG is undefined.
RETURN VALUE
       No value is returned.
CONFORMS TO
       ANSI - C
BUGS
       assert() is implemented as  a  macro;  if  the  expression
       tested  has side - effects, program behaviour will be dif-
       ferent depending on whether NDEBUG is  defined.  This  may
       create  Heisenbugs  which go away when debugging is turned
       on.
