boost::lock_guard vs boost::mutex::scoped_lock

Question

Which is preferred boost::lock_guard or boost::mutex::scoped_lock?

I\'m using Boost.Thread with the hope to move to C++11 threading when it

Answer 1

Amit is right: boost::mutex::scoped_lock is a typedef for boost::unique_lock, not lock_guard. scoped_lock is not available in C++0x.

Unless you need the flexibility of unique_lock, I would use lock_guard. It is simpler, and more clearly expresses the intent to limit the lock to a defined scope.
