Member Function Documentation

◆ Command()

bool TorControlConnection::Command	(	const std::string &	cmd,
		const ReplyHandlerCB &	reply_handler
	)

Send a command, register a handler for the reply.

A trailing CRLF is automatically added. Return true on success.

Definition at line 178 of file torcontrol.cpp.

Here is the caller graph for this function:

◆ Connect()

bool TorControlConnection::Connect	(	const std::string &	tor_control_center,
		const ConnectionCB &	connected,
		const ConnectionCB &	disconnected
	)

Connect to a Tor control port.

tor_control_center is address of the form host:port. connected is the handler that is called when connection is successfully established. disconnected is a handler that is called when the connection is broken. Return true on success.
