SETRBUF(3PVM) PVM Version 3.4 SETRBUF(3PVM)NAMEpvm_setrbuf - Switches the active receive buffer and saves the previous buffer.SYNOPSISC int oldbuf = pvm_setrbuf( int bufid ) Fortran call pvmfsetrbuf( bufid, oldbuf )PARAMETERSbufid Integer specifying the message buffer identifier for the new active receive buffer. oldbuf Integer returning the message buffer identifier for the previous active receive buffer.DESCRIPTIONThe routine pvm_setrbuf switches the active receive buffer to bufid and saves the previous active receive buffer oldbuf. If bufid is set to 0 then the present active receive buffer is saved and no active receive buffer exists. A successful receive automatically creates a new active receive buffer. If a previous receive has not been unpacked and needs to be saved for later, then the previous bufid can be saved and reset later to the active buffer for unpacking. The routine is required when managing multiple message buffers. For example switching back and forth between two buffers. One buffer could be used to send information to a graphical interface while a second buffer could be used send data to other tasks in the application.EXAMPLESC: rbuf1 = pvm_setrbuf( rbuf2 ); Fortran: CALL PVMFSETRBUF( NEWBUF, OLDBUF )ERRORSThese error conditions can be returned by pvm_setrbuf PvmBadParam giving an invalid bufid. PvmNoSuchBuf switching to a non-existent message buffer.SEE ALSOpvm_setsbuf(3PVM) 30 August, 1993 SETRBUF(3PVM)
