PCAP_STRERROR(3)

💖 pcap_strerror: the errno-to-string bestie 💖

okay so welcome to the PCAP_STRERROR(3) page, from the Library Functions Manual — yes bestie, we're doing C library lore today and it's actually iconic ✨

✨ NAME ✨

pcap_strerror — convert an errno value to a string 💅

🌸 SYNOPSIS 🌸

#include <pcap/pcap.h>

const char *pcap_strerror(int error);

🦋 DESCRIPTION 🦋

ok so pcap_strerror() returns an error message string that corresponds to error. That's it. That's the whole assignment. 💖

Internally it uses either strerror(3) or its thread-safe variant if one is available — and currently that's the case in every supported OS, no cap. So you get your little error message string, and the library handles the "do we have the safe version?" vibe check for you 🌈.

💀 BACKWARD COMPATIBILITY 💀

Heads up bestie, this one has a past. pcap_strerror 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 time-traveling to older libpcap, keep that in mind — fr fr 😭
