Description

The generic function dde-server-request is called in response to a request transaction. A method specializing on the classes of server and topic should return the data in item.

The expected format of the data is given by format, which defaults to :text. The set of supported formats may be extended in future releases, so applications should always check the value of the format parameter and reject transactions which use formats not supported by the application.

If the request fails, nil should be returned.
