A factory function, which creates a new Socket, immediately initiates connection with socket.connect(), then returns the net.Socket that starts the connection.
When the connection is established, a 'connect' event will be emitted on the returned socket. The last parameter connectListener, if supplied, will be added as a listener for the 'connect' event once.
Possible signatures:
- createConnection
- createConnection for
IPCconnections. - createConnection for TCP connections.
The connect function is an alias to this function.
