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
       ldiv, lldiv — compute quotient and remainder of a long division


SYNOPSIS
       #include <stdlib.h>

       ldiv_t ldiv(long numer, long denom);
       lldiv_t lldiv(long long numer, long long denom);


DESCRIPTION
       The  functionality  described  on  this  reference  page is aligned with the ISO C standard. Any conflict
       between the requirements described  here  and  the  ISO C  standard  is  unintentional.  This  volume  of
       POSIX.1‐2008 defers to the ISO C standard.

       These  functions  shall  compute the quotient and remainder of the division of the numerator numer by the
       denominator denom.  If the division is inexact, the resulting quotient  is  the  long  integer  (for  the
       ldiv()  function) or long long integer (for the lldiv() function) of lesser magnitude that is the nearest
       to the algebraic quotient. If the result cannot be represented, the  behavior  is  undefined;  otherwise,
       quot * denom+rem shall equal numer.


RETURN VALUE
       The  ldiv()  function  shall  return  a  structure  of  type ldiv_t, comprising both the quotient and the
       remainder. The structure shall include the following members, in any order:

           long   quot;    /* Quotient */
           long   rem;     /* Remainder */

       The lldiv() function shall return a structure of type lldiv_t,  comprising  both  the  quotient  and  the
       remainder. The structure shall include the following members, in any order:

           long long   quot;    /* Quotient */
           long long   rem;     /* Remainder */
