usage: r_fwait opflg eflag ltime Lunit

R_FWAIT is a REALTIME operator. It waits for completion of asynchronous data I/O initiated by a previous call to R_FREAD or R_FWRITE for the open file identified by LUNIT. If no I/O is pending for LUNIT this operator returns immediately. LUNIT must refer to a file that has previously been opened by a call to R_FOPEN. If LUNIT is missing it defaults to 1.
