What's the point of this?
If you are writing a C program, get a C book and learn all about argc and argv.
Of you know a good C book, post about it to HN.
If your aren't writing a C program, this is irrelevant.
Why does HN every day pull a random page from a manual and vote it to the front page? This is a terrible way to learn anything.
This is the best way though to meet some guys who never wrote a book, but are competent enough to delve into details that barely any book mentions. If you want to know one thing deep, sure, get a book or two. But if you want to create your understanding on numerous topics (wide learning), your way is a very long journey that might not even end before you retire. I don't think someone learns here as in a class, we just discuss matters of our interests. You start with replying to tfa, and then it turns more and more whatever it turns into. Nothing new for a forum-like, really, many do not even need clickable headlines, since they do not click on them.
