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.
