kupl_get_wtime

Get the current time (unit: second).

Interface Definition

int kupl_get_wtime();

Return Value

Return the current time (unit: second).

Examples

#include <stdio.h>
#include <assert.h>
#include <unistd.h>
#include "kupl.h"

int main()
{
    double start = kupl_get_wtime();
    usleep(1000001);
    double end = kupl_get_wtime();
    assert(end - start >= 1);
    return 0;
}

The preceding example demonstrates how to obtain the current time (unit: second).
The kupl_get_wtime function gets the current time. The time interval is obtained by calculating the difference between the return values of two distinct calls to this function.
