I need a function that provides milisecond-resolution delay in rt task.do you know any?
At least a function that works in gcc.Thank you any help in advance.

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.

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

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?

> so, what can I use that provides milisecond resolution at least.?

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().
