Empty for loop

I just came across a for(;;) while reading through MSDN on winsock.

What is the purpose of an empty for(;;) loop? Can not the exact same thing be accomplished with a while loop? Seems like tomayto-tomahto to me. If there is some significant purpose though, I'd much like to know.

Why is everyone in /prog/ a faggot? 20 posts and nobody explains what the acronym meant, meanwhile whining about /b/(the very reason this board has any users FYI). 
IHBT= I have been trolled
YHBT= You have been trolled
HIBT= Have I been trolled?
etc.
It was assumed you know what this meant because this is a very common expression around /prog/. Since for some reason many people feel the need to troll up /prog/(probably since 4chan and /b/ are the troll hotspots of the internet).  The majority of threads here are some form of obvious trolling/copypasta/spam.  Even if the thread is legitimate, it quickly gets over-run by trolls and spammers who endlessly repeat stupid unfunny memes.  Excuse my ranting, I just wish /prog/ didn't suck so much.  Some light moderation and the removal of all but the "code" bbcode tag could quickly put an end to the worst of it and allow actual discussion.
