GAI_STRERROR(3P)

✨ GAI_STRERROR(3P) ✨

okay bestie, welcome to the POSIX Programmer's Manual — this one's called gai_strerror, and it's lowkey the translator bestie of the networking world 💅

🌸 PROLOG 🌸

This manual page is part of the POSIX Programmer's Manual. Heads up though, fr fr: the Linux implementation of this interface may differ (so go check the corresponding Linux manual page for the deets on Linux behavior), or the interface may not even be implemented on Linux. not me finding that out the hard way 😭

👑 NAME 👑

gai_strerror — address and name information error description. it's giving "tell me what went wrong in human words" ✨

---

🎀 SYNOPSIS 🎀

#include <netdb.h>

const char *gai_strerror(int ecode);

---

💖 DESCRIPTION 💖

So basically, gai_strerror() shall return a text string describing an error value for the getaddrinfo() and getnameinfo() functions listed in the <netdb.h> header. it's the group chat translator for error codes, no cap 🫶

When the ecode argument is one of these values listed in the <netdb.h> header:

• [EAI_AGAIN]
• [EAI_BADFLAGS]
• [EAI_FAIL]
• [EAI_FAMILY]
• [EAI_MEMORY]
• [EAI_NONAME]
• [EAI_OVERFLOW]
• [EAI_SERVICE]
• [EAI_SOCKTYPE]
• [EAI_SYSTEM]

the function return value shall point to a string describing the error. iconic behavior honestly 💅

If the argument is not one of those values, the function shall return a pointer to a string whose contents indicate an unknown error. like "idk her" but in C 😭

---

⭐ RETURN VALUE ⭐

Upon successful completion, gai_strerror() shall return a pointer to an implementation-defined string. yep, that's the whole vibe.
