Documentation
startup :: ClientOptions -> IO RawFrontend Source #
Set up and start the main loop providing input and output.
Because of Windows and OS X, SDL2 needs to be on a bound thread, so we can't avoid the communication overhead of bound threads.
frontendName :: String Source #
The name of the frontend.
Internal operations
data FrontendSession Source #
Session data maintained by the frontend.
