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



PROLOG
       This manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may dif-
       fer (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 division of the numerator numer by the denomi-
       nator 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 quo-
       tient. 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 */
