Thread safe implementation of circular buffer

Question

Circular_buffer from boost library is not thread-safe. So I wrapped boost::circular_buffer object in a class as shown below. Mutual exclusion between the threads is achieved

Answer 1

Yes.
If you lock all the public methods with the same lock it will be threadsafe.

You could consider using read-write locks, which may have better performance if you have a lot of concurrent readers.

If you don't have a lot of readers, it will just add overhead, but may be worth checking the option and testing.
