The daemon management API.


All member functions are asynchronous. The function sends a request to the daemon and returns control. Once the response from the daemon is received via onDataAvailable(), the corresponding function of the class instance, set via setEventHandler(), is called. setEventHandler must be called before any other non-static member.


Use either connect() or getSocketPath() static member functions to establish connection with daemon via local socket. You have to manage the socket yourself. You should organize read loop (see onDataAvailable) and error handling.


EveusbEventHandler::writeToDaemon/readFromDaemon is called if EveusbController requests read/write operations on a socket that you manage.


Members return zero if command is sent to the daemon, otherwise error code.
