ml_qa_setpriority

Sets the priority of a message.

Parameters
Item Description Remarks
1 Message ID VARCHAR(128). You can obtain the message ID from ml_qa_createmessage or ml_qa_getmessage.
2 Priority INTEGER
Remarks

The QAnywhere API defines ten levels of priority value, with 0 as the lowest priority and 9 as the highest. Clients should consider priorities 0-4 as gradations of normal priority and priorities 5-9 as gradations of expedited priority.

You cannot alter this header after the message has been sent.
