[Winpcap-users] RE: capture AND send packets on same device

[Mark Buchanan]

Use 'pcap_loop(adhandle, 0, packet_handler, NULL);' where
'packet_handler' is the call back function that gets called when a
packet comes in. 

The callback function is then:
'void packet_handler(u_char *param, const struct pcap_pkthdr *header,
const u_char *pkt_data)'

You can call the function:
'(pcap_sendpacket(adhandle,packet,PacketLength)'
anytime to send out on the wire.
