define-dde-server

Defines a class for a Lisp DDE server.

define-dde-server class-name service-name => class-name

define-dde-server class-name superclasses slot-specs options => class-name

class-name

A class name.

service-name

A string.

superclasses

A list of superclasses.

slot-specs

The specifications for the class' slots.

options

A keyword option.

class-name

A class name.

The macro define-dde-server defines a class for a Lisp DDE server. The class inherits from dde-server.

The long form of the macro is similar to defclass, but with one extra option, :service, which is used to specify the service name string to which this server will respond.

The short form is provided to handle the common simple case; class-name is the name of the Lisp class to be defined, and service-name is the service name string to which this server will respond.

The first example uses the short version of define-dde-server to define a class, called lisp-server, which has the service name "LISP".

The second example shows how to use the long for of the macro to define the same class, and illustrates the use of the superclasses and options arguments.

(define-dde-server lisp-server (dde-server)

  ()

  (:service "LISP"))
