Hello,
i am getting messages from queue with mqseries_get procedure. And when queue is empty im getting COMPCODE = MQSERIES_MQCC_OK and REASON = MQSERIES_MQRC_NO_MSG_AVAILABLE, closing connection and all goes fine.
But when there is a message in a queue i'm getting Segmentation fault error.
Please advice me where to look for the root of this issue. I found some error files in /var/mqm/errors, but i dont know what to look at. There are only messages about long user name that exceeds 13 characters.
| Code: |
$mdg = [];
$gmo = ['Options' => MQSERIES_MQGMO_FAIL_IF_QUIESCING | MQSERIES_MQGMO_WAIT, 'WaitInterval' => 3000];
$bufferLength = 2000000;
$dataLength = 0;
$this->message = null;
mqseries_get($this->hConn, $this->hObj, $mdg, $gmo, $bufferLength, $this->message, $dataLength, $this->compCode, $this->reason);
|
The message body less than 2000000 bytes.
Thanks in advance. |

If mqseries_get is like the MQ API function MQGET, it assumes that the message buffer is pre-allocated.

These two things seems contradictory.
Have you viewed the example here.
Cheers,

if somebody wants to read all the messages:
| Code: |
while (true) {
$MQMD = array();
$gmo = array('Options' => MQSERIES_MQGMO_FAIL_IF_QUIESCING | MQSERIES_MQGMO_WAIT | MQSERIES_MQGMO_BROWSE_NEXT, 'WaitInterval' => 3000);
mqseries_get...
if ($comp_code == MQSERIES_MQCC_OK) {
echo $msg;
} else {
break;
}
}
