PCAP_FILE(3PCAP)                                        PCAP_FILE(3PCAP)

NAME         top

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

SYNOPSIS         top

       #include <pcap/pcap.h>

       FILE *pcap_file(pcap_t *p);

DESCRIPTION         top

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

       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().
