Just set a pointer to it:

/*stuff here*/
void* ptr=0x40800000;
/*stuff here*/

Be sure you own that memory... Or, for that matter, that the memory exists...

What are you trying to do, exactly? For most of the memory jobs there are other, better ways

i need to change the video output to composite. So I have to change the values of memory base address 0x40800000 with offset co4 and c08. What other methods can I use? :confused:

Sounds like a job for assembly language to me! hmmm... I think it's www.linuxassembly.org (http://www.linuxassembly.org) - but the link is in this forum somewhere! (or at CCAE (http://www.codeexample.org)).
