| Allegro CL version 8.2 Unrevised from 8.1 to 8.2. 8.1 version |
Arguments: &key (name *service-name*) (topics *service-topics*) (server-port-class (quote server-port))
Establishes the current Lisp process as a DDE server. Any DDE client program can thereafter (until close-server or close-dde is called) connect to this server by specifying the service name indicated by the name argument and one of the topics indicated by the topics argument.
A service name or topic may be either a string or a symbol, though they are always passed between programs as strings. When a symbol, its symbol-name is used to communicate with other programs.
The name argument defaults to the value of
*service-name*
, which initially is
the symbol :allegro
, meaning that a DDE client
program would specify the service name as "allegro" to connect to the
Lisp DDE server. The topics argument defaults to
the value of *service-topics*
, which initially
is the list of symbols (nil :system, :eval)
,
meaning that a DDE client program would specify either "nil",
"system", or "eval" as the topic in order to connect to the Lisp DDE
server.
server-port-class is the name of the class that
should be instantiated internally whenever a DDE client program
connects to this DDE server. The default is
server-port (naming the class server-port
). It may be useful to
pass the name of a server-port
subclass that you have created in
order to specialize a dde-message method on that
subclass.
The functions service-name and service-topics may be called later to retrieve the values that were most recently specified as the open-server arguments in a particular process.
Any Lisp process can act as only a single DDE server, though DDE client programs may each open multiple client ports to it.
See dde.htm for information about DDE support.
