linux sleeping with clock_nanosleep

Question

I want to use clock_nanosleep for waiting of 1 microsec.. As far as I understand, I have to give an absolute time as input. Is the following code okay in this case?

sample code::

void mysleep_ms(int milisec)
{
    struct timespec res;
    res.tv_sec = milisec/1000;
    res.tv_nsec = (milisec*1000000) % 1000000000;
    clock_nanosleep(CLOCK_MONOTONIC, 0, &res, NULL);
}

this is monotonic clock based sleep function. please refer it.
