MCI_DGV_RESERVE_PARMSA structure (digitalv.h)

The MCI_DGV_RESERVE_PARMS structure contains information for the MCI_RESERVE command for digital-video devices.

Syntax

typedef struct {
  DWORD_PTR dwCallback;
  LPSTR     lpstrPath;
  DWORD     dwSize;
} MCI_DGV_RESERVE_PARMSA;

Members

dwCallback

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

lpstrPath

Pointer to a null-terminated string containing the location of a temporary file. The buffer contains only the drive and directory path of the file used to hold recorded data; the filename is specified by the device driver.

dwSize

Size of reserved disk space.

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_RESERVE_PARMS as an alias which 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 not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
