ldiv(), lldiv()
QNX SDP8.0C Library ReferenceAPIDeveloper
Perform division on long or long long integers
Synopsis:
#include <stdlib.h>
ldiv_t ldiv( long int numer,
long int denom );
lldiv_t lldiv( long long numer,
long long denom );
Arguments:
- numer
- The numerator.
- denom
- The denominator.
Library:
libc
Use the -l c option to qcc to link against this library. This library is usually included automatically.
Description:
The ldiv() and lldiv() functions calculate the quotient and remainder of:
numer / denom
Returns:
A structure of type ldiv_t that contains the following members:
typedef struct {
long int quot; /* quotient */
long int rem; /* remainder */
} ldiv_t;
or a structure of type lldiv_t that contains the following members:
typedef struct {
long long quot; /* quotient */
long long rem; /* remainder */
} lldiv_t;
Examples:
#include <stdio.h>
#include <stdlib.h>
void print_time( long ticks )
{
ldiv_t sec_ticks;
ldiv_t min_sec;
sec_ticks = ldiv( ticks, 100 );
min_sec = ldiv( sec_ticks.quot, 60 );
printf( "It took %d minutes and %d seconds.\n",
min_sec.quot, min_sec.rem );
}
int main( void )
{
print_time( 86712 );
return EXIT_SUCCESS;
}
produces the output:
It took 14 minutes and 27 seconds.
