WrapTransportListener wraps a raw transport . Listener in an iconn . Listener . If sk is not provided transport encryption is disabled . The Listener will accept connections in the background and attempt to negotiate the protocol before making the wrapped connection available to Accept . If the negotiation and handshake take more than AcceptTimeout the connection is dropped . However note that once a connection handshake succeeds it will wait indefinitely for an Accept call to service it ( possibly consuming a goroutine ) . The context covers the listener and its background activities but not the connections once returned from Accept . Calling Close and canceling the context are equivalent . The returned Listener implements ListenerConnWrapper .
