The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

MCI_OVLY_SAVE_PARMS
 
        The MCI_OVLY_SAVE_PARMS structure contains the information
        for the MCI_SAVE message for video overlay devices. When
        assigning data to the fields in this data structure, set the
        corresponding MCI flags in the dwFlags parameter of
        mciSendCommand to validate the fields.
 
        typedef struct {
            DWORD dwCallback;
            LPCSTR lpfilename;
            RECT rc;
        } MCI_OVLY_SAVE_PARMS;
 
Parameters
        DWORD dwCallback

            Specifies a far pointer to the buffer containing a null-
            terminated string.
