PCAP_STRERROR(3PCAP)

✨ PCAP_STRERROR 💅

okay so this is a page from 3PCAP (that's the libpcap manual, iykyk) and honestly it's a short one but it's lowkey iconic so let's go 🫶

🌸 NAME 🌸

pcap_strerror — turn an errno value into a string, bestie. that's the whole job. ✨

🦋 SYNOPSIS 🦋

#include <pcap/pcap.h>

const char *pcap_strerror(int error);

🎀 DESCRIPTION 🎀

so here's the vibe: this function returns an error message string that corresponds to error. like, you hand it your sad little errno number and it hands you back words. the way that works?? 🥰

under the hood it uses either strerror(3) or its thread-safe variant if one is available — and ngl, that's currently the case in every supported OS. so you're covered, periodt. 👑

💜 BACKWARD COMPATIBILITY 💜

okay so history lesson, gather round 🧚 this function was not thread-safe in libpcap before 1.8.1 on Windows, and in libpcap before 1.10.5 on all other OSes. so if you're on ancient libpcap, thread safety was giving absolutely not. 💀 keep that in mind if you're doing anything multithreaded on the old stuff!
