Re: Thread Checking the Queue data in an infinite loop

I disagree with Joe (above), and think that your proposal (using an event to
signal a thread that's WaitForSingleObject on the event) is just fine.

Hello,

I have a Thread which runs in a while(1) infinite loop checking for
any data in the Queue(normal STL::Queue) and if any data is there, it
retrieves and does some functionality with it. Now since it is an
infinite loop, continousy checking for data, CPU Utilization is almost
95-100% for my process. To Avoid that, I have tempororily put
Sleep(1). But I know this is not a good solution.

I want to replace it with this Solution. Please let me know if this is
correct.

1) I will create a Synchronization Object i.e an Event Object which
is an Autoreset Event Object.

2) The threads which write the data to the Queue (There are 2 threads
writing data to the queue simoultaneously..Queue writing is
synchronized with a mutex) will set the Event Object (Set the state to
signalled)

3) The Thread which reads the Queue data will do a WaitForSingleObject
waiting for the Event Object to be signalled. So it will be in a idle
state (waiting) if there is no data in the queue.
So I can avoid CPU Utilization(100%) problem.

Please let me know whether my solution is proper or should I have to
use seperate Event Objects.?
