who have the sample souce code use C++ call PJSIP?

[gangban.lau@xxxxxxxxx (Gang Liu)]

Liusheng,
    You can do this way.

     pjcallback.h
     class PjCallback {
     public:
             PjCallback() {}
             ~PjCallback() {}

             void OnIncomingCall();
     }

     extern "C" void pjcallback_on_incoming_call_wrapper(pjsip_rx_data
*rdata);

     pjcallback.cpp
     #include "pjcallback.h"

     void PjCallback::OnIncomingCall(pjsip_rx_data *rdata)
     {
           // do something
     }

     PjCallback mycb();       // you can put this somewhere

    void pjcallback_on_incoming_call_wrapper(pjsip_rx_data *rdata)
    {
         mycb.onIncomingCall();
    }

    then you can call "pjcallback_on_incoming_call_wrapper" from pjsip
module's callback func.

regards,
Gang
