Scoped Lock> The Scoped Lock is a powerful idiom in C++.> A Scoped Lock acquires a mutex in its constructor, and releasesthe mutex in its destructor.> Thus, a scoped lock at the beginning of a block is the perfect wayto implement a critical section.> At the beginning of the block, in the construction of thescoped lock, the mutex is acquired.> No matter how the block is exited (normally, by return, or byexception), the destructor of the scoped lock ensures therelease of the mutex.
