2.12 div—divide two integers

Synopsis

     #include <stdlib.h>
     div_t div(int n, int d);
     

Description
Divide n/d, returning quotient and remainder as two integers in a structure div_t.

      typedef struct
      {
       int quot;
       int rem;
      } div_t;

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

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

No supporting OS subroutines are required.
