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 */
