# tibemsMsg_GetPriority

Function

## Purpose

Get the priority header from a message.

## C Declaration

    tibems_status tibemsMsg_GetPriority(
        tibemsMsg message,
        tibems_int* value );

## COBOL Call

    CALL "tibemsMsg_GetPriority"
         USING BY VALUE message,
               BY REFERENCE value,
               RETURNING tibems-status
    END-CALL.

Note: `message` has usage pointer.

## Parameters

Parameter | Description
--- | ---
`message` | Get the priority from this message.
`value` | Store the priority.

## Remarks

Sending calls record the priority of a message in this header, based on either a property of the producer, or on a parameter to the send call.

The JMS specification defines ten levels of priority value, from zero (lowest priority) to 9 (highest priority). The specification suggests that clients consider 0–4 as gradations of normal priority, and priorities 5–9 as gradations of expedited priority.

Priority affects the order in which the server delivers messages to consumers (higher values first). The JMS specification does not require all providers to implement priority ordering of messages. (EMS supports priorities, but other JMS providers might not.)
