DDHAL_GETSCANLINEDATA (Windows Embedded CE 6.0)
1/6/2010
This structure returns the scan line. This structure passes the information to the DirectDraw hardware abstraction layer (DDHAL) LPDDHAL_GETSCANLINE callback function.
Syntax
typedef struct _DDHAL_GETSCANLINEDATA {
LPDDRAWI_DIRECTDRAW_GBL lpDD;
DWORD dwScanLine;
HRESULT ddRVal;
} DDHAL_GETSCANLINEDATA;
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.
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.
