    tibems_long* value );

COBOL Call

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

Parameters

Parameter Description
message Get the expiration from this message.
value Store the expiration.

Remarks

Sending calls record the expiration time (in milliseconds) of the message in this field:

  • If the time-to-live is non-zero, the expiration is the sum of that time-to-live and the sending client’s current time (GMT).
  • If the time-to-live is zero, then expiration is also zero—indicating that the message never expires.

The server discards a message when its expiration time has passed. However, the JMS specification does not guarantee that clients do not receive expired messages.
