Member Function Documentation

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.

Here is the caller graph for this function:

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

Connect to a Tor control port.

target 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.
