CComObjectRootEx::InternalRelease
Decrements the reference count of a nonaggregated object by 1.
ULONG InternalRelease( );
Return Value
In both non-debug and debug builds, this function returns a value which may be useful for diagnostics or testing. The exact value returned depends on many factors such as the operating system used, and may, or may not, be the reference count.
Remarks
If the thread model is multithreaded, InterlockedDecrement is used to prevent more than one thread from changing the reference count at the same time.
