IUnknown::Release

Decreases the reference count of the interface by 1.

ULONG Release();

Parameters

None.

Return Values

Returns the new reference count. This value is for diagnostic and testing purposes only.

Remarks

The object that exports the interface deallocates itself when its total reference count reaches 0. Use the IUnknown::AddRef method to increase the interface's reference count by 1.

Applications must call this method to release only those interfaces that were explicitly created in a previous call to IUnknown::AddRef, IUnknown::QueryInterface, or a creation function such as Direct3DCreate9.
