pvm_setsbuf(3) |
 |
pvm_setsbuf − Switches the active send buffer.
|
C |
int oldbuf = pvm_setsbuf( int bufid ) |
|||
|
Fortran |
call pvmfsetsbuf( bufid, oldbuf ) |
|
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. |
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.
C:
|
sbuf1 = pvm_setsbuf( sbuf2 ); |
Fortran:
|
CALL PVMFSETSBUF( NEWBUF, OLDBUF ) |
These error
conditions can be returned by pvm_setsbuf
PvmBadParam
giving an invalid bufid.
PvmNoSuchBuf
switching to a non-existent message buffer.
