Name: IUnknownRelease()
Description:
This function takes a tick from a plugin instance's reference count.
When the reference count goes down to zero the object self-destructs.
Input Parameters:
obj - The 'this' pointer.
Output Parameters:
None. Return Value:
ULONG - Updated value of the reference count, or zero
in case of an error.
