The question is not clear. You hint at another rttask, does it mean that
you are using fifos among kernel space tasks?

If so do no use fifos anymore for kernel space applications in RTAI, but
mailboxes, typed mailboxes, POSIX pqueues, inter task messages. They are
simpler and more flexible in use.
In RTAI fifos are kept only for compatibility reasons and to allow a
generic communication with interrupt handlers.

Note that in RTAI you do not need fifos even if you want to communicate
to user space. In fact LXRT allows you to use all RTAI services
simmetrically inter-intra kernel and user space processes.

Ciao, Paolo.
