How to lock Queue variable address instead of using Critical Section?

I have 2 threads and global Queue, one thread (t1) push the data and another one(t2) pops the data, I wanted to sync this operation without using function where we can use that queue with critical section using windows API.

The Queue is global, and I wanted to know how to sync, is it done by locking address of Queue?

Is it possible to use Boost Library for the above problem?

One approach is to have two queues instead of one:

• The producer thread pushes items to queue A.
• When the consumer thread wants to pop items, queue A is swapped with empty queue B.
• The producer thread continues pushing items to the fresh queue A.
• The consumer, uninterrupted, consumes items off queue B and empties it.
• Queue A is swapped with queue B etc.

The only locking/blocking/synchronization happens when the queues are being swapped, which should be a fast operation since it's really a matter of swapping two pointers.
