Can't the argument be something like u64 instead of struct timespec,
regardless of this discussion (relative vs absolute)?


void mysleep(int msec) {
struct timeval tv;
tv.tv_sec = msec/1000;
tv.tv_usec = msec%1000;


void mysleep(int msec) {
poll(0, 0, msec*SOME_TIME_SCALE_VALUE);

That to say: struct time{spec,val,whatever} is more difficult to use than
plain numbers.

But yes... existing struct timespec has an advantage of being already existed.
Oh well.
