Hi everyone,
I'm just wondering, is it ever necessary/desireable to explicitly free memory
allocated by libpcap (using free() or similar)?
For example, each time pcap_dispatch() or pcap_loop() calls the packet handler
function, a (u_char *) pointer to the new packet data is passed to the packet handler;
once I'm done with the packet, should I free() this memory? Should I do the same for
the (struct pcap_pkthdr *) pointer that is also passed to the packet handler function?
Or, do pcap_dispatch() and pcap_loop() automatically free the memory once the packet
handler function returns? If so, what about pcap_next()?
Thanks,
Nick
