Hello People 
I know from previous code that I have 15 channels. But when I try running this code, I only get an item count of 1.
Any ideas why ?
| Code: |
mqAddString(requestsBag, MQCACH_CHANNEL_NAME, MQBL_NULL_TERMINATED, "*", &completionCode, &reasonCode);
mqExecute(connection, MQCMD_INQUIRE_CHANNEL_NAMES, MQHB_NONE, requestsBag, responseBag, MQHO_NONE, MQHO_NONE,
&completionCode, &reasonCode);
mqCountItems(responseBag, MQHA_BAG_HANDLE, &itemCountInBag, &completionCode, &reasonCode);
printf("Found %d items in bag\t", itemCountInBag); |
puzzled, Asad. |

You get bag a bag containing a bag - Look at the amqsailq sample, modified its something like (ignore the trim to the qname length, its just a very quick hack):
mqCountItems(responseBag, MQHA_BAG_HANDLE, &numberOfBags, &compCode, &reason);
CheckCallResult("Count number of bag handles", compCode, reason);
for ( i=0; i<numberOfBags; i++)
{
int numchls = 0;
int j;
/***********************************************************************/
/* Get the next system bag handle out of the mqExecute response bag. */
/* This bag contains the queue attributes */
/***********************************************************************/
mqInquireBag(responseBag, MQHA_BAG_HANDLE, i, &qAttrsBag, &compCode, &reason);
CheckCallResult("Get the result bag handle", compCode, reason);
mqCountItems(qAttrsBag, MQCACH_CHANNEL_NAMES, &numchls, &compCode, &reason);
CheckCallResult("Count number of bag handles", compCode, reason);
/***********************************************************************/
/* Get the queue name out of the queue attributes bag */
/***********************************************************************/
for (j=0; j<numchls; j++) {
mqInquireString(qAttrsBag, MQCACH_CHANNEL_NAMES, j, MQ_Q_NAME_LENGTH, qName,
&qNameLength, NULL, &compCode, &reason);
mqTrim(MQ_Q_NAME_LENGTH, qName, qName, &compCode, &reason);
printf("%4ld %-48s\n", qDepth, qName);
}
