RT-FIFOs are not full-duplex. One side reads, the another writes.
For full-duplex, one needs to use a buffer for each direction.
With RT-FIFOs, this means two of them.
Note, that you can present two RT-FIFOs as one full-duplex device on the
user level (you also get separate read and write handlers when you do).
Please see the man page for the rtf_make_user_pair function.
