It isbased on the Real-Time Linux RT-FIFO mechanism.  Thertf_* functions are used by the real-time tasks; Linux processes usestandard character device access functions such as.BR read(2) ,.BR write(2) ,and.BR select(2) ..SH "RETURN VALUE"On success, 0 is returned.  On failure, a negative value is returnedas described below..SH ERRORS.IP \fB-EINVAL\fP.I fifois not a valid RT-FIFO identifier..SH "AUTHOR"Jerry Epplin <JerryEpplin@worldnet.att.net>.SH "SEE ALSO".BR rtf_ipc_create (2), .BR rtf_receive (2), .BR rtf_send (2)
