Values

Description

Each COM interface pointer has a reference count which is used by the server to control its lifetime. The function release should be called whenever a reference to interface-ptr is being removed. The function invokes the COM method IUnknown::Release so the form (release ptr) is equivalent to using call-com-interface as follows:

(call-com-interface (ptr i-unknown release))

Examples

(release p-foo)
