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 different depending on whether
NDEBUG
is defined. This may create Heisenbugs which go away when debugging is turned on.
