PCAP_MAJOR_VERSION(3PCAP)PCAP_MAJOR_VERSION(3PCAP)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);
Ifp refers to a ``savefile'',pcap_major_version() returns the major number of the file format of the ``savefile'' andpcap_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). Ifp refers to a live capture, the values returned bypcap_major_version() andpcap_minor_version() are not meaningful.
