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.
