PCAP_MAJOR_VERSION(3)					     Library Functions Manual					     PCAP_MAJOR_VERSION(3)

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.
