IDDVideoPortContainer

Applications use the methods of the IDDVideoPortContainer interface to create and manipulate DirectDrawVideoPort objects. Retrieve a pointer to this interface by calling the IUnknown::QueryInterface method of a DirectDraw object, specifying the IID_IDDVideoPortContainer reference identifier.

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:

IUnknown 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;
