PCAP_FILE(3PCAP)                                                                            PCAP_FILE(3PCAP)



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().
