## IDDVideoPortContainer

Applications use the methods of the IDDVideoPortContainer interface to create and manipulate DirectDrawVideoPort objects.

The methods of the IDDVideoPortContainer interface can be organized into the following groups:

Creating objects | CreateVideoPort
Video ports | EnumVideoPorts
| QueryVideoPortStatus
Connections | GetVideoPortConnectInfo

The IDDVideoPortContainer interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:

AddRef |
QueryInterface |
Release |

You can use the LPDDVIDEOPORTCONTAINER data type to declare a variable that contains a pointer to an IDDVideoPortContainer interface. The Dvp.h header file declares the LPDDVIDEOPORTCONTAINER with the following code:

typedef struct IDDVideoPortContainer FAR *LPDDVIDEOPORTCONTAINER;
