pcap_major_version, pcap_minor_version - get the version number of a savefile
#include <pcap/pcap.h>
int pcap_major_version(pcap_t *p);
int pcap_minor_version(pcap_t *p);
If p refers to a ``savefile'', pcap_major_version() returns the
major number of the file format of the ``savefile'' and
pcap_minor_version() 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 pcapng).
If p refers to a live capture, the values returned by
pcap_major_version() and pcap_minor_version() are not
meaningful.
