Hi, I am receiving message thru a raw socket using recvfrom. I have set the IP_PKTINFO flag by int on=1; setsockopt(sd,SOL_IP,IP_PKTINFO,&on,sizeof(on)); this call succeeds. But i want to know the info stored in struct ip_pktinfo. I receive the message using recvfrom. BUt man page of recvfrom says " If from is not NULL, and the socket is not connection-oriented, the source address of the message is filled in. " But i specifically need the interface index which is present in the ip_pktinfo structure. How to do it. Kindly help me in this regard. Thanks, Ramesh - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
