Creating work_queue class

Let's call the functional object that takes no arguments (a task, for short).

typedef boost::function<void()> task_t; 

Now, imagine a situation where we have threads that post tasks and threads that execute posted tasks. We need to design a class that can be safely used by both types of those threads. This class must have functions for:

• Getting a task or waiting for a task till it is posted by another thread
• Checking and getting a task if we have one (returning an empty task if no tasks remain)
• Posting tasks

Getting ready

Make sure that you feel comfortable with boost::thread or std::thread , know basics of mutexes, and are aware of boost::function or std::function.
