Need some information on how memory on heap is managed

I have the following scenario

1. On CC3200LP server waiting for incoming connection.

2. Accept client connection

3. Spawn a new thread to handle connection in this way

	void InitTCPServer(int socket_id){

		Task_Params taskParams;

    		Task_Params_init(&taskParams);
		taskParams.stackSize = TASKSTACKSIZE;
		taskParams.stack = new char[TASKSTACKSIZE];
		taskParams.priority = 1;
		taskParams.arg0 = (xdc_UArg)new CThreadTCPClientHandle(socket_id);

    		Task_construct(new Task_Struct, (Task_FuncPtr)CThreadTCPClientHandle::Create, &taskParams, NULL);

	}
	
4. When client close connection thread terminate

   How handle free the heap memory created with new char[TASKSTACKSIZE], new Task_Struct and  

   (xdc_UArg)new CThreadTCPClientHandle(socket_id)?

   Are they automatically freed when Thread Terminate?	

Thanks Regards
