.. code:: cpp
  
    template <typename T, typename Allocator>
    bool operator==( const concurrent_queue<T, Allocator>& lhs,
                     const concurrent_queue<T, Allocator>& rhs );
          
Checks if ``lhs`` is equal to ``rhs``, that is they have the same number of elements and ``lhs``
contains all elements from ``rhs``.

**Returns**: ``true`` if ``lhs`` is equal to ``rhs``; ``false``, otherwise.

.. code:: cpp

    template <typename T, typename Allocator>
    bool operator!=( const concurrent_queue<T, Allocator>& lhs,
                     const concurrent_queue<T, Allocator>& rhs );

Equivalent to ``!(lhs == rhs)``.

**Returns**: ``true`` if ``lhs`` is not equal to ``rhs``; ``false``, otherwise.
