Unlike ACE_Task, these class doesn't have the ability to be a part of a Stream chain. I.e. You cannot (yet) chain modules based on ACE_Task_Ex.
template class ACE_Task <ACE_SYNCH_USE, ACE_Message_Block> : public ACE_Task_Base { // put here the good old ACE_Task code };
When User (and legacy code) write ACE_Task<ACE_MT_SYNCH>, specialized ACE_Task code is in action.

Initialize a Task, supplying a thread manager and a message queue. If the user doesn't supply a ACE_Message_Queue pointer then we'll allocate one dynamically. Otherwise, we'll use the one passed as a parameter. |

Flush the task's queue, i.e., free all of the enqueued message blocks and releases any threads blocked on the queue. Note that if this conflicts with the C++ iostream function, just rewrite the iostream function as ::. Definition at line 50 of file Task_Ex_T.inl.
