The amount of arrogance here is astounding. For one thing it's a trope that Linux doesn't have good documentation, RHEL has better docs than anything I've seen from BSD. C is a whole software language and AFAIK you can't just "man c" and even if you could why would you want to read the whole manual/handbook for the C programming language to figure out something trivial? You would google it anyway.
The only reason using man pages on BSD might be better than google is because 90% of the answers you'll find on google will be from a Linux perspective and you'll have to do a second search to figure out how to apply the answer to BSD. Yes, 90% of the time the Linux solution will work on BSD but the 10% of the time when it doesn't is a huge pain.
