* IDirectDraw7::QueryInterface
|
||||
*
|
||||
* Queries different interfaces of the DirectDraw object. It can return
|
||||
* IDirectDraw interfaces in version 1, 2, 4 and 7, and IDirect3D interfaces
|
||||
* in version 1, 2, 3 and 7. An IDirect3DDevice can be created with this
|
||||
* method.
|
||||
* The returned interface is AddRef()-ed before it's returned
|
||||
*
|
||||
* Used for version 1, 2, 4 and 7
|
||||
*
|
||||
* Params:
|
||||
* refiid: Interface ID asked for
|
||||
* obj: Used to return the interface pointer
|
||||
*
|
||||
* Returns:
|
||||
* S_OK if an interface was found
|
||||
* E_NOINTERFACE if the requested interface wasn't found
