It has two advantages: you don't have to invent a name for a variable that you are never going to use, and you don't have to add braces to limit the scope of the lock. Very meager advantages, IMHO: it doesn't bother me to just throw in any short name (e.g. 'l') in such cases, and if the function is large enough to require the extra braces, it's probably too large and complicated anyway. But I'm not the only programmer in the world, and some people seem to actually like it. And... I'll use it too, in quick hacks in throw-away code. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=29834
