Member Function Documentation

void firevision::FuseNetworkTransceiver::recv	(	fawkes::StreamSocket *	s,
		FuseNetworkMessageQueue *	msgq,
		unsigned int	max_num_msgs = 8
	)		[static]

Receive data.

This method receives all messages currently available from the network, or a limited number depending on max_num_msgs. If max_num_msgs is 0 then all messages are read. Note that on a busy connection this may cause recv() to never return! The default is to return after 8 messages. The messages are stored in the supplied message queue.

Parameters:

s	socket to gather messages from
msgq	message queue to store received messages in
max_num_msgs	maximum number of messages to read from stream in one go.

Exceptions:

ConnectionDiedException

Thrown if any error occurs during the operation since for any error the conncetion is considered dead.

void firevision::FuseNetworkTransceiver::send	(	fawkes::StreamSocket *	s,
		FuseNetworkMessageQueue *	msgq
	)		[static]

Send messages.

Parameters:

s	socket over which the data shall be transmitted.
msgq	message queue that contains the messages that have to be sent

Exceptions:

ConnectionDiedException
