ASSERT(3P)		   POSIX Programmer's Manual		    ASSERT(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the	 corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.

NAME
       assert - insert program diagnostics

SYNOPSIS
       #include <assert.h>

       void assert(scalar expression);

DESCRIPTION
       The assert() macro shall insert diagnostics  into  programs;  it	 shall
       expand  to a void expression. When it is executed, if expression (which
       shall have a scalar type) is false (that	 is,  compares	equal  to  0),
       assert()	 shall write information about the particular call that failed
       on stderr and shall call abort().

       The information written about the call that failed  shall  include  the
       text of the argument, the name of the source file, the source file line
       number, and the name of the enclosing function; the latter are, respec‐
       tively,	the  values  of the preprocessing macros __FILE__ and __LINE__
       and of the identifier __func__.

       Forcing a definition of the name NDEBUG, either from the compiler  com‐
       mand  line  or  with  the preprocessor control statement #define NDEBUG
       ahead of the #include <assert.h> statement, shall stop assertions  from
       being compiled into the program.

RETURN VALUE
       The assert() macro shall not return a value.

ERRORS
       No errors are defined.
