typedef struct {

Members
dwCallback
The low-order word specifies a window handle used for the MCI_NOTIFY flag.

lpfilename

Identifies the area of the video buffer to update. RECT structures are handled differently in MCI than in other parts of Windows; in MCI, rc.right contains the width of the rectangle and rc.bottom contains its height.

Remarks
When assigning data to the members of this structure, set the corresponding flags in the fdwCommand parameter of the mciSendCommand function to validate the members.
