I, as most developers, appreciate well commented code. But as others have mentioned you are going a bit too far. // The user has given and illegal number or type of arguments. The program // usage is printed to the standard error stream and we exit abnormally. fprintf(stderr, USAGE); exit(EX_USAGE); What else is it supposed to be? This is, even for me who does not use C(++) on a regular basis, obvious. It looks like you are interested in writing well documented code. I think a good example you can learn a lot from is Redis[1].
