   For example, 
	Firstly, I have known the below:
	unsigned char * pBuff; ( the pointer to data buffer, it is successfully initiated at before)  
    int      nBuffLen=230400; (320*240*3)
	int      nFrameWidth=320;
	int      nFrameHeight=240;
	int      nPixedBpp=24; (Frame data's Format type : RGB24    i.e.3 bytes)
	
	Secondly, I want to fill the video image into the whole window which is 640(width)*480(heigh), how to write the code? Should I build a SDL_Surface which is 320*240*24 or 640*480*24?
	 
	Thanks a lot.

	

        
Best Regards
