close-dde

Arguments: &rest ignore

Closes all DDE client and server ports that were opened in the current process by calling open-port and/or open-server. This is done automatically by the OS when Lisp or a standalone DDE Lisp application exits, but perhaps it is desirable to call this function explicitly to clean up no-longer-used resources.

See dde.htm for information about DDE support.
