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
       These functions shall compute the quotient and remainder of  the  divi-
       sion  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, compris-
       ing  both  the  quotient and the remainder. The structure shall include
       the following members, in any order:

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