This is how the forwarder signals Intercept:
191 // Ordinary message requiring forwarding
192 if (pMsg->addr == TOS_LOCAL_ADDRESS) { // Addressed to local node
193 if ((signal
Intercept.intercept[id](pMsg,&pMHMsg->data[0],PayloadLen)) == SUCCESS)
{
194 pMsg = mForward(pMsg,id);
195 }
196 }
197 else {
198 // Snoop the packet for permiscuous applications
199 signal Snoop.intercept[id](pMsg,&pMHMsg->data[0],PayloadLen);
200 }
201
You need to write a handler for this event in your application after
wiring the Intercept interface to your application. It is similar to
capturing a Timer.fired() event.
