Members
- lpDD**
Pointer to the DDRAWI_DIRECTDRAW_GBL structure that represents the DirectDraw object. - dwScanLine**
Indicates the number of the scan line. - ddRVal**
Passes the DirectDraw return values. - GetScanLine**
Used by DirectDraw and should not be filled in by the driver.
Remarks
The returned scan line value in dwScanLine must be between 0 and <n>, where scan line 0 is the first visible scan line on the screen and <n> is the last visible scan line, plus any scan lines that occur during vblank. For example, in a case where you are running at a screen resolution of 640x480, and you have 12 scan lines during vertical blank, the values returned to GetScanLine range from 0 to 491.
