Is there a way to get better timing resolution on UNIX OS

Sleep has 1 second resolution. I've heard about using select. Any details

Thanks

Use select() with NULL-Pointers for rfds,wfds,xfds, and specify the desired
time
in the timeval-structure (last parameter).

Remark: This works in a similar way for poll().

See also: Some systems have the usleep() call.

Here's a simple implementation of usleep() using select()

void usleep (unsigned int useconds)
{
  struct timeval delay;

  delay.tv_sec = 0;
  delay.tv_usec = useconds;

  select (0, NULL, NULL, NULL, &delay);

        Just do a "man select" and all your questions will be answered ;-)

How about usleep()?
