| In my application i am using MQGMO_SET_SIGNAL during an MQGET.And i am getting MQRC_SIGNAL1_ERROR as return code. In that case, what may be the reason for an invalid address in Signal1 field. Or why it can't point to a read-only storage. Is there any way to avoid this return code ? |

Signalling is unsupported on a lot of platforms, and should be avoided.
Use a Get with timed wait in a loop, instead.

| Whether by using this wait option, can the wait interval be interuppted. For eg: my wait interval is 10 secs and once any message is available in the queue at 6th sec, then whether that wait interval will be cancelled ?? |

Short answer, Yes.
Longer answer, The Get will return to your application as soon as a message is available, or when the interval has expired. You will also want to specify the FAIL IF QUIESCING option on the get.

Have you considered using triggering so that your application will only be launched once a message has arrived?
