MCI_DGV_RESTORE_PARMSW structure (digitalv.h)
The MCI_DGV_RESTORE_PARMS structure contains information for the MCI_RESTORE command for digital-video devices.
Syntax
typedef struct {
DWORD_PTR dwCallback;
LPWSTR lpstrFileName;
POINT ptOffset;
POINT ptExtent;
RECT rc;
} MCI_DGV_RESTORE_PARMSW;
Members
dwCallback
The low-order word specifies a window handle used for the MCI_NOTIFY flag.
lpstrFileName
Pointer to a null-terminated string containing the filename from which the frame buffer information will be restored.
ptOffset
ptExtent
rc
Rectangle containing positioning information. 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.
Note
The digitalv.h header defines MCI_DGV_RESTORE_PARMS as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
