NAME
       assert - verify program assertion

SYNOPSIS
       #include <assert.h>

       void assert(int expression);

DESCRIPTION
       The  assert()  macro  inserts  diagnostics into applications. When exe‐
       cuted, if expression is FALSE (zero), assert() prints the error message

	 Assertion failed: expression, file xyz, line nnn

       on the standard error output and aborts. In the error message,  xyz  is
       the  name  of  the  source  file	 and nnn the source line number of the
       assert() statement. These are respectively the values of the preproces‐
       sor macros __FILE__ and __LINE__.

       Since  assert()	is implemented as a macro, the expression may not con‐
       tain any string literals.

       Compiling with the preprocessor option -DNDEBUG or with the  preproces‐
       sor  control  statement #define NDEBUG ahead of the #include <assert.h>
       statement, will stop assertions from being compiled into the program.

       Messages printed from this function are in the native  language	speci‐
       fied by the LC_MESSAGES locale category. See setlocale(3C).
