Function

Summary

Connects a sink interface pointer to the source of events in another COM interface pointer.

Package

com

Signature

interface-connect interface-ptr iid sink-ptr &key errorp => cookie

Arguments

interface-ptr

A COM interface pointer that provides the source interface iid.

iid

The iid of the source interface to be connected. The iid can be a symbol naming the interface or a refguid foreign pointer.

sink-ptr

A COM interface that will receive the events for the iid.

errorp

A boolean. When false, errors connecting the sink-ptr will cause nil to be returned. Otherwise an error of type com-error will be signaled.

Values

cookie

An integer cookie associated with this connection.

Description

Connects the COM interface sink-ptr to the connection point in interface-ptr that is named by iid.

Example

Suppose there is an interface pointer clonable which provides a source interface i-clonable-events, then the following form can be used to connect an implementation of this source interface sink:

(setq cookie

      (interface-connect clonable

                         'i-clonable-events

                         sink))
