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.

Oh wow, I thought this was a joke, but it's true.

What the fuck is wrong with them?
