PCAP_FILE(3)               Library Functions Manual               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(), or NULL, if a network
       device was opened with pcap_create() 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().
