No, i meant returning the freed pointer and copying straight away into 
s'thing else, i did assume that was quite safe as i can't see what else 
could get access to that part of the memory before the copy, but later
i thought that bad things could happen if another program gets a slice 
and overwrites that memory, rightly assuming it's free(which it would be).

eg: strcpy(myval,foo());
..which would be very inefficient to say the least.                        
                        
Anyway problem solved , thanks again.
