bitwise right shipt on unsigned char * | ERROR

[simly01]

Hi EveryOne,

I am having problem oprating bitwise right shift, which is >> on unsigned char *. Do you know why here is my code...

Please help !!!!!!!!!!!!!!

	DWORD ImageSize = ((DWORD)bmfh.bfSize-sizeof(BITMAPFILEHEADER));
	LPBYTE pImage = (LPBYTE)malloc(ImageSize);
	memcpy(pImage,pbmih,ImageSize);	

    
	if(!pImage){
		return FALSE;
	}	

	/*int index = 0;
	rgb_picture image;
	

   for (index=0; index<256; index++)
    {
           /******* Problem starts right here**********/
          /*********pImage >>= 2    ***************/

		// get the red component
	    strcpy(reinterpret_cast<char *>(&image.palette[index].red),reinterpret_cast<char *>(pImage >>= 2));

		// get the green component
	    strcpy(reinterpret_cast<char *>(&image.palette[index].green),reinterpret_cast<char *>(pImage >>= 2));

		// get the blue component
	    strcpy(reinterpret_cast<char *>(&image.palette[index].blue),reinterpret_cast<char *>(pImage >>= 2));

    } // end for index
	
	FILE *fpr,*fpg,*fpb;

	
	if (((fpr=fopen("red","wb"))==NULL) || ((fpg=fopen("green","wb"))==NULL) || ((fpb=fopen("blue","wb"))==NULL))
		return -1;

	if (fwrite(((void *)image.palette[index].red),256,1,fpr)!=1)
		return -1;

	if (fwrite(((void *)image.palette[index].green),256,1,fpg)!=1)
		return -1;

	if (fwrite(((void *)image.palette[index].blue),256,1,fpb)!=1)
		return -1;*/

I don't understand what you're doing... And, I gotta get going... so I apologize if I'm on the wrong track...

Are you trying to bit-shift a pointer??? Because it seems to me that would be a weird thing to do. What are you trying to do? Are you decreasing color levels by right-shifting? Maybe you're not de-referencing the pointer?

Are you trying to shift a pixel? If so, bit-shifting is not what you want to do.

And what is the problem? Compile error? Wrong results?
