sleep(unsigned int seconds) doesn't take fractions of seconds.

I don't understand what you mean. Do you want to use a dedicated 
hardware timer? How do you think sleep() works?

The very first question for you is: Do you want to delay a task 
execution under the control of Xenomai or Linux? For Xenomai I already 
pointed you to the API. For the latter, you could use nanosleep().

Please see the Xenomai API at:
http://www.xenomai.org/documentation/branches/v2.4.x/html/api/index.html
and the description of your favourite Xenomai skin. Normally, you even 
have a nanosecond resolution.

> At least a function that works in gcc.

What do you mean with "works in gcc"? Xenomai and its applications are
compiled with gcc so where is the problem?
