Hi Philippe,
Thanks for the information. Does the message queue API can only be used
between kernel sapce and user space only? How about from user space
task to another user space task?
Regards,
John

Also works. The uniform queue descriptor blurs the kernel/user-space and process
boundaries. It should be seen as a communication endpoint.

We are in the process of calibrating Xenomai native API message queue
performance in user space application. Does anybody has sample code to
share with us?
