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 pcap-NG).

If p refers to a live capture, the values returned by pcap_major_version() and pcap_minor_version() are not meaningful.
