Hi!

	I need something like memcpy(),
but with inverted direction flag. So that
the dest. pointer points to the end of the used
memory, not to the beginning. I need the
same for memset(), too.

	This can't be that hard, but
a) I'm not fluid in ASM, especially not with DJGPP,
b) have no ASM books here at work, and
c) have only the bins of DJGPP v2, so I can't look
   into the source of the above mentioned funcs.

I need these funcs to blit an bitmap mirrored to the
screen.

Any help welcome...

Lenny
