mqseries_back — MQSeries MQBACK

Using mqseries_back() only works in conjunction with mqseries_begin() and only function when connecting directly to a Queueu manager. Not via the mqclient interface.
Connection handle.
This handle represents the connection to the queue manager.
Completion code.
Reason code qualifying the compCode.
No value is returned.
Example #1 mqseries_back() example
<?php
mqseries_back($conn, $comp_code, $reason);
if ($comp_code !== MQSERIES_MQCC_OK) {
printf("CompCode:%d Reason:%d Text:%s<br>\n", $comp_code, $reason, mqseries_strerror($reason));
}
?>
Note: mqseries_back() will not function when using MQSeries Client to connect to a Queueu Manager.
