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

       #include <pcap/pcap.h>

       FILE *pcap_file(pcap_t *p);

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

       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()	when  passed  the
       return value of pcap_file().
