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 net-
work 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().

pcap_fileno - get the file descriptor for a live capture
SYNOPSIS
#include <pcap/pcap.h>
int pcap_fileno(pcap_t *p);
DESCRIPTION
If p refers to a network device that was opened for a live capture using a combination of pcap_create() and pcap_activate(), or using
pcap_open_live(), pcap_fileno() returns the file descriptor from which captured packets are read.
If p refers to a ``savefile'' that was opened using functions such as pcap_open_offline() or pcap_fopen_offline(), a ``dead'' pcap_t opened
using pcap_open_dead(), or a pcap_t that was created with pcap_create() but that has not yet been activated with pcap_activate(), it
returns -1.

Hi all,
I'm writing a program using libpcap, and I have multiple pcap files in a folder that I want to capture.
I currently have
handle = pcap_open_offline("/data/traffic/pcap1.pcap", errbuf");
which works fine since pcap_open_offline() takes in a filename. However, I want to process... (0 Replies)
Hi Folks,
i got the following Problem: I want to make an analysis on a pcap file. (diestance between different packets and so on) The difficulty now... it's not a simple Ethernet/ IP/ File, but it's a SS7 file.
There are the Layers MTP2 MTP3 and ISUP. My analysis depends on the ISUP Layer.
