ldiv—divide two long integers #include <stdlib.h>
ldiv_t ldiv(long n, long d);
Description
Divide
n/d,
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.
