Really ? POSIX spec describes as below:
Under no circumstance shall the operation fail with a timeout
if a message can be removed from the message queue immediately.
http://pubs.opengroup.org/onlinepubs/009604499/functions/mq_receive.html
My reading of this is that timeout error must not be returned
when message can be performed immediately. What do you think of it ?
Regards,
