Usage
Pointer is a pointer to OLE’s IUnknown interface. You can use
IUnknown::QueryInterface to get other interface pointers.
When you call GetNativePointer, PowerBuilder calls OLE’s AddRef
function, which locks the pointer. You can release the pointer in your DLL
function or in a PowerBuilder script with the ReleaseNativePointer
function.
