pvmfsetsbuf
SETSBUF(3PVM) PVM Version 3.4 SETSBUF(3PVM)NAME
pvm_setsbuf - Switches the active send buffer.
SYNOPSIS
C int oldbuf = pvm_setsbuf( int bufid )
Fortran call pvmfsetsbuf( bufid, oldbuf )
PARAMETERS
bufid Integer the message buffer identifier for the new active send buffer. A value of 0 indicates the default receive buffer.
oldbuf Integer returning the message buffer identifier for the previous active send buffer.
DESCRIPTION
The routine pvm_setsbuf switches the active send buffer to bufid and saves the previous active send buffer oldbuf. If bufid is set to 0
then the present active send buffer is saved and no active send buffer exists.
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.
EXAMPLES
C:
sbuf1 = pvm_setsbuf( sbuf2 );
Fortran:
CALL PVMFSETSBUF( NEWBUF, OLDBUF )
ERRORS
These error conditions can be returned by pvm_setsbuf
PvmBadParam
giving an invalid bufid.
PvmNoSuchBuf
switching to a non-existent message buffer.
