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
       labs, llabs - return a long integer absolute value
SYNOPSIS
       #include <stdlib.h>
       long labs(long i);
       long long llabs(long long i);

DESCRIPTION
       The labs() function shall compute the absolute value of the long  inte-
       ger operand i. The llabs() function shall compute the absolute value of
       the long long integer operand i. If the result cannot  be  represented,
       the behavior is undefined.
RETURN VALUE
       The labs() function shall return the absolute value of the long integer
       operand. The labs() function shall return the  absolute  value  of  the
