ldiv---divide two long integers

Synopsis

#include <stdlib.h>
ldiv_t ldiv(long n, long d);

Description
Divide returning quotient and remainder as two long integers in a structure ldiv_t.

Returns
The result is represented with the structure

 typedef struct
 {
  long quot;
  long rem;
 } ldiv_t;

where the quot field represents the quotient, and rem the remainder. For nonzero d, if `r = ldiv(n,d);' then n equals `r.rem + d*r.quot'.

To divide int rather than long values, use the similar function div.

Portability
ldiv is ANSI.

No supporting OS subroutines are required.
