MCI_OVLY_LOAD_PARMS structure

The MCI_OVLY_LOAD_PARMS structure contains information for the MCI_LOAD command for video-overlay devices.

Syntax

typedef struct {
  DWORD_PTR dwCallback;
  LPCTSTR   lpfilename;
  RECT      rc;
} MCI_OVLY_LOAD_PARMS;

Members

dwCallback

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

lpfilename
