From: Ivan Brugiolo [MSFT] on 11 Jun 2007 12:47 Not all the DrvXXX functions exposed by a display driver are `drawing` functins, but, most of them are. You can conceivably immagine that DrvLineTo is expected to draw a line. -- -- This posting is provided "AS IS" with no warranties, and confers no rights.

From: Attributesoft on 11 Jun 2007 13:06 Ok I understood how I can move data across use-mode and session space. Now I need to find how I can copy those changed areas and then pass through DrvEscape to user-mode app. How can I do that?
From: Attributesoft on 11 Jun 2007 13:49 I mean how I can copy Bitmap from surface?
From: Ivan Brugiolo [MSFT] on 11 Jun 2007 16:25 memcpy(pDestinationBuffer,SURFOBJ::pvBits,SURFOBJ::cjBits); Honestly, you should try to understand what you are trying to do before shooting questions. -- -- This posting is provided "AS IS" with no warranties, and confers no rights.

Yes I understand that, but I need to know when for example DrvLineTo occurs, before this function or after does it change surface or not? Sorry for not correct English. Thank you for your answer. |
