PCAP_MAJOR_VERSION(3PCAP)PCAP_MAJOR_VERSION(3PCAP)NAME
pcap_major_version, pcap_minor_version - get the version number of a savefile
SYNOPSIS
#include <pcap/pcap.h>
int pcap_major_version(pcap_t *p);
int pcap_minor_version(pcap_t *p);
DESCRIPTION
If p refers to a ``savefile'', pcap_major_version() returns the major number of the file format of the ``savefile'' and pcap_minor_ver-
sion() returns the minor number of the file format of the ``savefile''. The version number is stored in the ``savefile''; note that the
meaning of its values depends on the type of ``savefile'' (for example, pcap or pcap-NG).
If p refers to a live capture, the values returned by pcap_major_version() and pcap_minor_version() are not meaningful.

pcap_open_offline, pcap_fopen_offline - open a saved capture file for reading
SYNOPSIS
#include <pcap/pcap.h>
char errbuf[PCAP_ERRBUF_SIZE];
pcap_t *pcap_open_offline(const char *fname, char *errbuf);
pcap_t *pcap_fopen_offline(FILE *fp, char *errbuf);
DESCRIPTION
pcap_open_offline() is called to open a ``savefile'' for reading.
fname specifies the name of the file to open. The file can have the pcap file format as described in pcap-savefile(5), which is the file
format used by, among other programs, tcpdump(1) and tcpslice(1), or can have the pcap-ng file format, although not all pcap-ng files can
be read. The name "-" in a synonym for stdin.
Alternatively, you may call pcap_fopen_offline() to read dumped data from an existing open stream fp. Note that on Windows, that stream
should be opened in binary mode.
RETURN VALUE
pcap_open_offline() and pcap_fopen_offline() return a pcap_t * on success and NULL on failure. If NULL is returned, errbuf is filled in
with an appropriate error message. errbuf is assumed to be able to hold at least PCAP_ERRBUF_SIZE chars.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin

I used to use ls -l cut to detrmine file size, and google searches didn't come up with anything else but 'stat' which doesn't appear on HPUX.
I discovered the humble 'wc -c' which does this job very neatly, and thought I would share it. (7 Replies)

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.
