PCAP_SET_SNAPLEN(3)

💖 NAME 💖

Hiii bestie! Welcome to pcap_set_snaplen(3) — that's the page name — from the Library Functions Manual. This one is all about setting the snapshot length for a not-yet-activated capture handle. Slay. ✨

🎀 SYNOPSIS 🎀

#include <pcap/pcap.h>

int pcap_set_snaplen(pcap_t *p, int snaplen);

🦋 DESCRIPTION 🦋

Okay so pcap_set_snaplen() sets the snapshot length that's gonna be used on a capture handle when the handle is activated. You pass that value in as snaplen, and the capture handle is p. Cute and straightforward. 💅

🌸 RETURN VALUE 🌸

pcap_set_snaplen() returns 0 on success. If you call it on a capture handle that has already been activated, it returns PCAP_ERROR_ACTIVATED. No cap, that's the whole return-value story. 🫶
