 
Disconnect a sink interface pointer from the source of events in another COM interface pointer.
A COM interface pointer that provides the source interface iid .
The iid of the source interface to be disconnected. The iid can be a symbol naming the interface or a 
refguid
 foreign pointer.
The integer cookie associated with the connection to be disconnected.
A boolean. When 
nil
, errors disconnecting the 
cookie 
will cause 
nil
 to be returned. Otherwise an error of type 
com-error
 will be signalled.
Disconnects the connection for cookie from the connection point in interface-ptr that matches iid .
Suppose there is an interface pointer 
clonable
 which provides a source interface 
i-clonable-events
, then the following form can be used to disconnect an implementation of this source interface with cookie 
cookie
:
(interface-disconnect clonable
'i-clonable-events
cookie)
