- request connection type #!rest argsprocedure
This creates a new message object (see below) with a tag and the given type. args are the message-contents. It then sends this request to the server and awaits a response. The response should match the request (a Twhatever should result in a Rwhatever message), or a condition of type (exn 9p-response-error) is signaled. If the server returns an error (via Rerror), a condition of type (exn 9p-server-error) is signaled. The response object (a message object) is returned.
