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.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it
