RE: Write System Pointer to User Space

For those C newbies.
Don't let this statement trick you into thinking you
have to write non-portable or ugly C. C language constructs
cause the compiler and translator to generate the required 
underlying instructions to keep the pointers valid 
(within reason).

Simple assignments and pointer arithmatic for example:
  struct1 = struct2
  spacePointer += 10
 


"It was a rigorous result in information theory that once you could 
learn in a sufficiently flexible manner - something humanity had achieved 
in the Bronze Age - the only limits you faced were speed and storage; 
any other structural changes were just a matter of style."
