Int_t TMonitor::GetActive ( Long_t timeout = -1 ) const

Return number of sockets in the active list.

If timeout > 0, remove from the list those sockets which did not have any activity since timeout millisecs. If timeout = 0, then reset activity timestamp on all active sockets. This time out is typically used if GetActive() is used to see how many remotes still need to send something. If they pass the timeout they will be skipped and GetActive() will return 0 and the loop can be exited.

Return number of sockets in the de-active list.

Definition at line 473 of file TMonitor.cxx.

TList * TMonitor::GetListOfActives ( ) const

Returns a list with all active sockets.

This list must be deleted by the user. DO NOT call Delete() on this list as it will delete the sockets that are still being used by the monitor.

TSocket * TMonitor::Select ( )

Return pointer to socket for which an event is waiting.

Select can be interrupt by a call to Interrupt() (e.g. connected with a Ctrl-C handler); a call to ResetInterrupt() before Select() is advisable in such a case. Return 0 in case of error.

TSocket * TMonitor::Select ( Long_t timeout )

Return pointer to socket for which an event is waiting.

Wait a maximum of timeout milliseconds. If return is due to timeout it returns (TSocket *)-1.

Return 0 in case of any other error situation.

Definition at line 348 of file TMonitor.cxx.

Int_t TMonitor::Select	(	TList *	rdready,

Set interest mask for socket sock to interest.

If the socket is not in the active list move it or add it there. If interest=kRead then we want to monitor the socket for read readiness, if interest=kWrite then we monitor the socket for write readiness, if interest=kRead|kWrite then we monitor both read and write readiness.

Definition at line 180 of file TMonitor.cxx.

void TMonitor::SetReady ( TSocket * sock )

private

Called by TSocketHandler::Notify() to signal which socket is ready to be read or written.

User should not call this routine. The ready socket will be returned via the Select() user function. The Ready(TSocket *sock) signal is emitted.
