It does appear that printf doesn't set errno, at least on linux and
OSX,
It probably will set errno if
1) it gets an error writing to the standard output (e.g., if it's
redirected to a file, and the file system is full or you're over quota)
or
2) it calls "isatty()

hallo,
i didn't go into much detail but for a start:
i'd make "pcap_t *pfd" global and change:
if (!(pcap_open_live(iface, snaplen, 0, -1, errbuf)))
to
if ((pfd = pcap_open_live(iface, snaplen, 0, -1, errbuf)) != NULL)
this should get you started :-)
good luck,

Hello, i'm attempting my first pcap capture, but pcap_loop segfaults, and i'm
not quite sure why:
-- begin ./sniff output --
xzziroz:/home/kspecial# ./sniff
-> successfuly listening on iterface 'eth0'
Segmentation fault
xzziroz:/home/kspecial# gdb sniff
