and using ftell(); that won't necessarily work on Windows (if libpcap was built with a different version of the C runtime library than tcpdump is), and, even on UN*X, would break if a pcap_dumper_t * were ever made something other than a FILE *. Provide a pcap_dump_ftell() implementation that does that cheating cast for use if libpcap doesn't have it (a pcap_dumper_t * is just a FILE * on those older versions of libpcap).
