Description

Synopsis

daedalusIPC :: Int -> IO ()

Arguments

:: Int	Port number to send to Daedalus
-> IO ()

Start up the Daedalus IPC process. It's called daedalusIPC, but this could be any nodejs program that needs to start cardano-wallet. All it does is reply with a port number when asked, using a very nodejs-specific IPC method.

If the IPC channel was successfully set up, this function won't return until the parent process exits. Otherwise, it will return immediately. Before returning, it will log an message about why it has exited.

TODO(KS): If you want to use TRACE here, you need to provide the trace functions as params OR provide a record of trace functions.
