The generic function
dde-server-topic
is called whenever a client attempts to make a connection to the server. The argument
topic-name
is a string identifying a topic. If the server recognizes the topic, a method specializing on the server should return an instance of one of the server's topic classes. If the server does not recognize the topic, the method should return
nil
.
