Yes No. Any additional feedback? I've been splunking around Dll loading recently for a pet project. It's been an interesting journey and this evening I solved the final piece of the puzzle and, when I did, I suddenly wondered, not for the first time, why Windows holds the loader lock when calling DllMain Categories : Geek Speak , Lock Explorer.

Loader lock doesn't actually have anything to do with threads, although they don't exactly help avoid it. Deadlock is a generic threading problem. HansPassant Yes i understand what a dead lock is. I am just trying to wrap my head around, what exactly is LoaderLock. Is it a special lock or what — brainydexter.

It is just a lock inside the Windows loader, held when it calls a DllMain entrypoint and ensures DllMain calls are serialized. It is not re-entrant so doesn't require a thread to bite.

You can always see it back in the stack trace, LdrLockLoaderLock is at the top of the stack if you really have a problem. Thanks HansPassant. That helped — brainydexter. Add a comment.
