Synopsis
--------

.. code:: cpp

    namespace oneapi {
        namespace tbb {
   
           class task_arena {
           public:
               void enqueue(task_handle&& h);

Member Functions
----------------

.. cpp:function:: void enqueue(task_handle&& h)   
     
Enqueues a task owned by ``h`` into the ``task_arena`` for procession.
 
Behavior of this function is identical to generic version (``template<typename F> void task_arena::enqueue(F&& f)``) except parameter type. 

.. note:: 
   ``h`` should not be empty to avoid undefined behavior.
