Problem with usleep's precision.

[bjorn rohde jensen]

Hi there,

  It sounds to me, like you want your program to sleep for
such a short time, there is no point in involving the OS
scheduler. If you really require such fine grained timing,
you will need to turn to a real-time OS or, if your application
can suffer a few missed dead-lines, use busy waiting on a
lightly loaded host.
  None of this has anything to do with gcc though. It is
strictly a platform issue;)

Yours sincerely,

Bjorn
