PCAP_MAJOR_VERSION(3PCAP)

💖 PCAP_MAJOR_VERSION 💖

okay so bestie, welcome to the 3PCAP corner of the manual, where we're talking about pcap_major_version and pcap_minor_version — yes they're two functions, yes they do almost the same thing, no you don't have to pick a favourite (but you will) 🎀

✨ 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 💅

okay so here's the tea. If p is pointing at a savefile, then pcap_major_version() hands you back the major number of that savefile's file format, and pcap_minor_version() hands you back the minor number of that savefile's file format. two lil' functions, one big job. 💖

and the version number? it's literally stored inside the savefile itself, no cap. but — and this is the part where you gotta pay attention — the meaning of those values depends on what type of savefile you're dealing with (for example, pcap or pcapng). so like, same numbers, different lore depending on the format. iykyk ✨

🫶 quick vibe check though: if p refers to a live capture, then the values that pcap_major_version() and pcap_minor_version() return are not meaningful. like, don't build your whole personality around them, they're not telling you anything real. 🙈
