declaration
I'm a novice..now i'm learning how to write a graphic program in C. I've browsed through the Web http://www.brackeen.com/home/vga/basics.html
and got stuck with these declarations :
typedef unsigned char byte;
byte far *VGA = (byte far*)0xA0000000L;
please help me.........i got an assignment from my lecturer that is too hard for me
typedef unsigned char byte;
this tells the compiler that byte is an alias for an unsigned char.
byte far *VGA = (byte far*)0xA0000000L;
far means that the memory address is a segment:offset address rather than a near pointer which is just an offset address.
(byte far*) is a cast.
0xA0000000L is the start of the video memory on vga systems.
Free the weed!! Class B to class C is not good enough!!
