      In Cloverleaf 6.1, Is there any way to have an inbound message translated by an Xlate, then reply after the Xlate in the same thread, or does it require a second thread to generate the reply?

      ie

      message inbound to thread 1 -> Xlate -> Continue and Reply Xlate -> Route continue to Thread X

      Or does it have to be:

      message inbound to thread 1 -> Xlate -> Continue to thread 2 -> thread 2 generates continue and reply -> Reply Xlate -> thread 1

          Perhaps reroute will help you.

          In the first Xlate cut 2 messages wiith the second message specifieed for reroute (you can specify that right in the Xlate if you want) then on the route definitions for the IB thread specify the reroute TrxID and a new Xlate with the destination being the ib_thread.

          That might work.

            Thanks Jim,

            Is there a sample anywhere for this case?

            Otherwise I’ll have a play to try figure it out.

              I have done the reroute via Xlate.

              I have not done the rest but it seems all the pieces should work.

              So do you need an example of how to do the reroute in an Xlate?

              The User Doc on 6.0.0 is pretty clear but if you want I can see what I have and send that to you. Send me an email so I have your email.

                Many thanks Jim for your help with this.

                I ended up going with using an Xlate with the following Post Proc in the Route Message section.

                The Xlate stores the relevant information in the USERDATA.

                The result will kill or continue depending on the fault status in the USERDATA, and a reply message is rerouted to the Route Replies.

                The reply is handled in the Route Replies section and can handle different replies based on TRX id.

                Code:

                proc XlateReplySplitter {args} {
                   global HciConnName
                   keylget args MODE       aMode
                   keylget args MSGID      aMsgId
                   keylget args CONTEXT    aContext
                   keylget args ARGS       aArgs
                   if {$aContext eq “xlt_post”} {
                       set myMsgId [msgcreate -type reply -recover [msgget $aMsgId]]
                       set myConn [msgmetaget $aMsgId SOURCECONN]
                       set myUserData [msgmetaget $aMsgId USERDATA]
                       set myDriverCtrl [msgmetaget $aMsgId DRIVERCTL]
                       set myTrxId “”
                       keylget myUserData TRX_ID myTrxId
                       msgmetaset $myMsgId SOURCECONN $myConn DESTCONN $myConn USERDATA $myUserData DRIVERCTL $myDriverCtrl

                       set myDisp “{REROUTE {{$myMsgId $myTrxId}}}”
                       set myFaultString “”
                       keylget myUserData FAULT_STRING myFaultString
                       if {$myFaultString eq “”} {
                           lappend myDisp “CONTINUE $aMsgId”
                       } else {
                           lappend myDisp “KILL $aMsgId”
                       }
                       return $myDisp
                   }
                }
