[Boost-users] scoped_lock

I think this is my own fault. I'm debugging some issues with multi-threading and using boost scoped_lock. My code looks like this: { // Enqueue the notification to be processed scoped_lock(m_notifications.lock); m_notifications.sources->push(note); } Am I correct in assuming this is not going to work as expected? The compiler might not even instantiate the lock given this code? I need to write it like this? { // Enqueue the notification to be processed scoped_lock locked(m_notifications.lock); m_notifications.sources->push(note); } Kind regards, Samuel
