Please read this link by the author of boost.thread:
He also has a personal blog worth reading:
concerning your specific questions:
1. boost::mutex::scoped_lock is just a typedef of unique_lock<mutex>
inside mutex. With this kind of typedef, you'll be able to use the same
type scoped_lock for other kind of mutex(
For example Timed_mutex ) by changing the mutex type only.
There IS the definition on this page:
2. " std::lock_guard is deliberately basic and can only be used as
shown. On the other hand, std::unique_lock allows for deferred locking,
trying to lock, trying to lock with a timeout, and unlocking before the
object is destroyed. "(copied from the first link above)
