DDVIDEOPORTSTATUS

The DDVIDEOPORTSTATUS structure describes the status of a video-port object. This structure is used with the IDDVideoPortContainer::QueryVideoPortStatus method.

typedef struct _DDVIDEOPORTSTATUS {
    DWORD dwSize;        // size of the structure
    BOOL  bInUse;        // TRUE if video port is currently being used
    DWORD dwFlags;       // not used
    DWORD dwReserved1;   // reserved for future use
    DDVIDEOPORTCONNECT VideoPortType;    // information about the connection
    DWORD dwReserved2;   // reserved for future use
    DWORD dwReserved3;   // reserved for future use
} DDVIDEOPORTSTATUS, *LPDDVIDEOPORTSTATUS;
