Applications use the methods of the IDDVideoPortContainerinterface to create and manipulate DirectDrawVideoPort objects. You retrieve a pointer to this interface by calling the IUnknown::QueryInterfacemethod of a DirectDraw object, specifying the IID_IDDVideoPortContainer reference identifier.
The methods of the IDDVideoPortContainerinterface can be organized into the following groups:
| Creating objects | CreateVideoPort |
| Video ports | EnumVideoPorts |
| QueryVideoPortStatus | |
| Connections | GetVideoPortConnectInfo |
The IDDVideoPortContainerinterface, like all COM interfaces, inherits the IUnknowninterface methods. The IUnknowninterface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
You can use the LPDDVIDEOPORTCONTAINERdata type to declare a variable that contains a pointer to an IDDVideoPortContainerinterface. The Dvp.h header file declares the LPDDVIDEOPORTCONTAINERwith the following code:
typedef struct IDDVideoPortContainer FAR *LPDDVIDEOPORTCONTAINER;
