PCAP_FILE(3)                                                      PCAP_FILE(3)




NAME

       pcap_file - get the standard I/O stream for a savefile being read


SYNOPSIS

       #include <pcap/pcap.h>

       FILE *pcap_file(pcap_t *p);


DESCRIPTION

       pcap_file()  returns  the standard I/O stream of the ``savefile,'' if a
       ``savefile'' was opened with pcap_open_offline(3), or NULL, if  a  net-
       work  device  was  opened  with pcap_create(3) and pcap_activate(3), or
       with pcap_open_live(3).

       Note that the Packet Capture library is usually built with  large  file
       support,  so the standard I/O stream of the ``savefile'' might refer to
       a file larger than  2  gigabytes;  applications  that  use  pcap_file()
       should,  if  possible, use calls that support large files on the return
       value of pcap_file() or the value returned by fileno(3) when passed the
       return value of pcap_file().
