DIV(3)                  NetBSD Library Functions Manual                 DIV(3)

div, ldiv, lldiv, imaxdiv -- quotient and remainder from division
Standard C Library (libc, -lc)
#include <stdlib.h> div_t div(int num, int denom); ldiv_t ldiv(long int num, long int denom); lldiv_t lldiv(long long int num, long long int denom); #include <inttypes.h> imaxdiv_t imaxdiv(intmax_t num, intmax_t denom);
These functions compute the value of num / denom and return the quotient and remainder in a specific divison structure. The functions differ only with respect to the type of the return value and the parameters. The returned structure always contains two members named quot and rem, denoting the quotient and the remainder. The type of these correspond with the underlying type of the function.
The following example demonstrates the basic usage of the functions. div_t d; int a = 4321; int b = 1234; d = div(a, b); (void)printf("%d %d\n", d.quot, d.rem);
