DESCRIPTION

14       If  p  refers  to  a  network device that was opened for a live capture
15       using a combination of pcap_create(3PCAP) and pcap_activate(3PCAP),  or
16       using  pcap_open_live(3PCAP), pcap_fileno() returns the file descriptor
17       from which captured packets are read.

19       If p refers to a ``savefile'' that was opened using functions  such  as
20       pcap_open_offline(3PCAP)   or   pcap_fopen_offline(3PCAP),  a  ``dead''
21       pcap_t opened using pcap_open_dead(3PCAP), or a pcap_t that was created
22       with  pcap_create() but that has not yet been activated with pcap_acti‐
23       vate(), it returns PCAP_ERROR.
