Hi,
ok i'm not a expert programmer, so if i get anything wrong
don't shout at me :)

Isn't it bad to return the address of a local varible...
once the function ends the varible will be taken from the
stack and the address would no longer be valide.

As ur other post stated you did actully malloc
the space?

lilke

int * results = (int *)malloc(sizeof(int));

right?

did you then at the end of the function free the
memory?

wouldn't that cause the memory location that the 
function returned become invalid?

would then it also mean the next time 
you call the function it allocates the same
peice of memory, therefore getting the
results u showed? 

Also is it strictly nessarey to use the
pointers...it mayde the function very messy...

Evan,
