ULONG UlRelease( LPVOID punk );
Parameters
- punk
-
[in] Pointer to an interface derived from the IUnknown interface, in other words any MAPI interface.
The reference count is the number of existing pointers to the object to be released.
If the punk parameter is NULL, the function returns immediately without calling IUnknown::Release
UlRelease returns the value returned by the IUnknown::Release method, which can be equal to the reference count for the object to be released.
For more information about IUnknown::Release, see Implementing the IUnknown Interface.
