# client-port

class, dde package

The class of all DDE ports for implementing a DDE client in lisp.

You can create a client-port by calling make-instance on the `client-port` class, and then open it by calling open-port on the client-port instance.

It may be useful to create and use a subclass of the `client-port` class in order to specialize a dde-message method on that subclass.

See dde.html for information about DDE support.

# dde-info

Class, dde package

The class of dde-info objects. The function dde-info returns the single dde-info instance for a process that might use the Allegro DDE facility. The dde-info object holds information about the general state of the DDE facility within a particular process.

See dde.html for information about DDE support.

# dde-port

class, dde package

The class of all DDE ports for implementing either a DDE client or a DDE server. See client-port and server-port for more information.

# server-port

class, dde package

The class of all DDE ports for implementing a DDE server in Lisp.

An application does not instantiate this class directly. Instead, an instance is created internally if the Lisp application has called open-server and then some other program connects to the Lisp DDE server as a client.

It may be useful to create a subclass of server-port in order to specialize a dde-message method on the subclass. The subclass name may be passed as the server-port-class argument to open-server to establish it as the server-port class that will be instantiated.

See dde.html for information about DDE support.
