hello,

Thank you for helping me solve my problem.

You recommend me to update to a more recent version. But I think the
xenomai version 2.6.0 is the lastest version over http://www.xenomai.org
 site.

By the way, i have a short question. When i make run cross-link program, i
don't understand why there is a leak memory. Even if, i try to remove all
parasite in while loop, but the leak memory is always constant. i think the
problem comes from rt_dev_write() or rt_dev_read() which don't release the
memory buffer. im wrong?
