rtf_flush empties the RT-FIFO fifo.
The RT-FIFO is a mechanism, implemented as a character device, to communicate between realtime tasks and ordinary Linux processes. The rtf_* functions are used by the realtime tasks; Linux processes use standard character device access functions such as read(2), write(2) and select(2).
N or P is greater than or equal to RTF_NO.
N or P is not a valid RT-FIFO identifier.
