Right I've got two putpixel routines, one for VESA 1.2 banked mode, the
other for VESA 2.0 Linear Frame Buffer Mode.

They are both implemented as macros now for speed purposes, although no
doubt inline would have much the same effect on performance.

However, I do not want to continuously have if statements all over my code
checking which routine should be used. So, I set up an array as such

void *putpixel[2](int x, int y, int c);

and call putpixel[0](0,0,15) for example or use 1 instead of 0 for the
second routine.

But can I inline them in any way? I realize that this would involve the
compiler knowing which routine would be used on each call, but I would know
that from after my mode setting routine!

Any help appreciated!

Thanx James.
