So if I want to alter codeMaker (located in main()) with the function read_unbuffered I should not use a pointer?
That's the precise opposite of what I just told you. You're confusing yourself with too much doublethink.
Pass a pointer to codeMaker into read_unbuffered. Just like the way dozens of stdio functions take a pointer to a buffer, to let them read or write to that buffer. That tells it what memory it should modify, so it can modify the contents of that array directly without passing anything back (because returning an array is nonsensical, and returning a pointer doesn't modify its contents, so both are useless in this context). As long as the memory's valid, a pointer to memory doesn't care about variable scope.

So, since the codeMaker[] in getcode() is local to getcode(), it is not affecting the codeMaker[] in main(), right?
Correct. It bears no resemblance to the example I showed you, however, which does modify variables outside itself. I'll flesh it out a little more.
