ibm mq series
 

I have one query regarding ibm mq series:

To open the MQ series queue I am using the API as follows:
MQOPEN (HCon, &od, MQOO_OUTPUT, &HObj, &CompCode, &Reason);

In "CompCode" it returns if the function is succeeded or not and in the "Reason" it returns the reason code specifying the reason.

But the problem is "Reason" is an integer but I want the actual reason in the string format i.e. actual error text (e.g. error string like "File not found").

So, does anybody know any function in IBM MQ series (just like perror()) to convert the "Reason" code to the actual error text?

Hi -

AFAIK, there is no equivalent of "perror ()" for IBM MQSeries. But it shouldn't be difficult to write one for yourself. The documentation you would need is on-line here:
Websphere MQ Application Programming Reference

'Hope that helps .. PSM

Do you mean,

void mq_perror (int reason_code, char *reason_string, int n)
{
switch (reason_code)
{
case MQRC_Q_MGR_NOT_AVAILABLE :
strncpy (reason_string, n, "Queue Manager not Available");
break;

case MQRC_REPORT_OPTIONS_ERROR :
strncpy (reason_string, n, "Invalid options in Report field in the message descriptor MQMD");
break;

and so on ...........
}
}

Hi, girish_hilage -

Yup: that's exactly what I mean.

One minor suggestion - mq_perror would be a lot more useful if it returned a pointer to your *reason buffer:That way, you could use it directly inside of "printf()", etc. Just a thought...

Yes. Thank you very much for your reply.
