MCI_DGV_STATUS_PARMSW structure (digitalv.h)
The MCI_DGV_STATUS_PARMS structure contains parameters for the MCI_STATUS command for digital-video devices.
Syntax
typedef struct {
DWORD_PTR dwCallback;
DWORD_PTR dwReturn;
DWORD dwItem;
DWORD dwTrack;
LPWSTR lpstrDrive;
DWORD dwReference;
} MCI_DGV_STATUS_PARMSW;
Members
dwCallback
The low-order word specifies a window handle used for the MCI_NOTIFY flag.
dwReturn
Buffer for return information.
dwItem
Identifies capability being queried.
dwTrack
Length or number of tracks.
lpstrDrive
Specifies the approximate amount of disk space that can be obtained by the MCI_RESERVE command.

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_STATUS_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.
