Re: [reSIProcate-users] Fwd: how to parse sip frag

[Scott Godin <sgodin@xxxxxxxxxxxxxxx>]

Here is some code from the recon project RemoteParticipant::processReferNotify that looks at the SipFrag body:

   SipFrag* frag  = dynamic_cast<SipFrag*>(notify.getContents());

   if (frag)

   {

      // Get StatusCode from SipFrag

      if (frag->message().isResponse())

      {

         code = frag->message().header(h_StatusLine).statusCode();

      }

   }

my source code for parse sip frag like this:

//subscription can be ended through a notify or a failure response.
void TSipAccount::onTerminated(ClientSubscriptionHandle h, const SipMessage* msg)
{
      
    if (msg != NULL && msg->exists(resip::h_Event) && msg->header(resip::h_Event).value() == "refer")
    {
        const Mime sipfrag_t("message", "sipfrag");
        int reason = 0;
        if (msg->exists(resip::h_ContentType) && msg->header(resip::h_ContentType) == sipfrag_t)
        {
            SipFrag frag(msg->getContents()->getBodyData(), msg->header(resip::h_ContentType));
            const SipMessage &fmsg = frag.message();
            if (!fmsg.isRequest())
            {
                reason = fmsg.header(h_StatusLine).statusCode();
  
            }
        }
       }
}


this compile is ok, but got link error, I found the constructor of SipFrag I used declared in SipFrag.hxx, but not implemented in SipFrag.cxx

so can anybody help to find out how to parse sipfrag?
