This example simply illustrates a cleaner way -of utilizing Message_Blocks to store objects rather than copying their -contents. -<P> -The ACE_Barrier class has been used in the Task class which blocks the -threads until all of them are rearing to go and grab a block from the -queue and process it. -<P> -Thus a message queue can be used to accomplish a variety of tasks by -storing a object pointer in the blocks. -</UL> -<P><HR WIDTH="100%"> -<CENTER>[<A HREF="../online-tutorials.html">Tutorial Index</A>] [<A HREF="page02.html">Continue This Tutorial</A>]</CENTER> - |
