I 'm registering an event handler function using MQCB and the starting the callback using MQCTL with MQOP_START_WAIT.
I have used MQOP_START_WAIT, since I want to keep the callback in the same Thread. (This is because I want to handle threads by my self.)
I have encountered an issue due to the above option.
I need to Suspend the CallBack after a particular time. (this is because, I need to stop listing to a particular queue after a particular time and hence need to deregister the queue).
Is there an option where I can introduce a TimeOut functionality to the callback.
Thanks in Advance. |

| I'm probably a little confused here, but if you want to halt the callback, I would think that you would merely close the queue. |

mqjeff,
To close the queue, I need to get out of the CallBack. But when MQCTL with MQOP_START_WAIT is used, that thread is allocated only for the callback and cannot do anything else in that thread.
So What I need is "getting out of the callback after a particular time".
That is why I asked whether there is a "TimeOut" functionality in MQ.
And isn't there a way of stopping the callback without terminating the Thread?
(when MQOP_START_WAIT is used) |

You can use the WaitInterval value of the MQGMO passed to the MQCB to periodically get the callback function called after the timeout.
Cheers,
Paul.
