#include <stdlib.h>lldiv_t lldiv(long long int numerator, long long int denominator);
lldiv( ) was added by C99.
The lldiv( ) function returns the quotient and remainder of the operation numerator / denominator in an lldiv_t structure. It is similar to ldiv( ) except that it operates on long long integers.
The structure type lldiv_t has these two fields:
long long int quot; /* quotient */ long long int rem; /* remainder */
Related functions are div( ) and ldiv( ).
