ARES_EXPAND_NAME(3)

✨ ARES_EXPAND_NAME(3) ✨

okay so bestie, welcome to the manual page for ARES_EXPAND_NAME(3) 💖 — which, plot twist, is all about the function called ares_expand_string. yeah, the page name and the function name don't match, it's giving mysterious, we move 💅

🌸 NAME 🌸

ares_expand_string — expand a length encoded string 🎀

🦋 SYNOPSIS 🦋

#include <ares.h>

int ares_expand_string(const unsigned char *encoded,
                       const unsigned char *abuf, int alen,
                       unsigned char **s, long *enclen)

💜 DESCRIPTION 💜

so what does ares_expand_string actually do? bestie it converts a length encoded string into a NUL-terminated C string. iconic behavior honestly ✨

• the argument encoded gives the beginning of the encoded string 🫶
• the arguments abuf and alen give the containing message buffer — and yes you need those, because they're necessary for the processing of indirection pointers within the encoded domain name 🔍
• the result lands in a NUL-terminated allocated buffer, and a pointer to it gets stored in the variable pointed to by s 💫
• the length of the encoded string gets stored in the variable pointed to by enclen, so the caller can advance past the encoded string to read further data in the message. main character energy: keep it moving 🚶♀️

no cap, that allocated buffer is yours now — there's a whole other manpage for freeing it, keep reading 👀

🔥 RETURN VALUES 🔥

ares_expand_string can return any of the following values:

• ARES_SUCCESS — expansion of the encoded string succeeded. slay! 🎉
• ARES_EBADSTR — the encoded string was malformed and could not be expanded. it's giving corrupted 😭💀
• ARES_ENOMEM — memory was exhausted. the vibes ran out of RAM 🙈
