IPV6_RECVERR(2const)

✨ IPV6_RECVERR ✨

okay bestie so this is a 2const page from the Linux man-pages (that's the manual, section 2, constant-flavored) and it's literally about extended reliable error message passing 💖 like that's the whole NAME, we're not being subtle here

---

📚 LIBRARY

Standard C library (libc, -lc). yep, the classic, we love her 🫶

---

🌸 SYNOPSIS

#include <netinet/in.h>  /* Definition of IP* constants */
#include <sys/socket.h>

int setsockopt(int sockfd, IPPROTO_IPV6, IPV6_RECVERR,
               const int *enable, sizeof(int));
int getsockopt(int sockfd, IPPROTO_IPV6, IPV6_RECVERR,
               int *enabled, sizeof(int));

not me just handing you the exact function signatures so you can copy-paste them 💅 do not freestyle these, okay?

🌈 DESCRIPTION

So basically: this controls receiving of asynchronous error options. That's it, that's the job 💀

• setsockopt() with IPV6_RECVERR → you pass a const int *enable and it turns the receiving of async error options on or off (the size is sizeof(int), keep it consistent bestie).
• getsockopt() with IPV6_RECVERR → you pass an int *enabled and it tells you whether it's currently on, again at sizeof(int).

For the actual deets on the behavior, you gotta go read IP_RECVERR(2const). This page is just the IPv6 flavored constant, she's pointing you to her sibling 🫶

💀 ERRORS

Like, where do you even look? The original says:

• See IPPROTO_IPV6(2const).
• See setsockopt(2).
• See ipv6(7).

that's the whole list, no notes ✨

👀 SEE ALSO

• IP_RECVERR(2const)

like a little friend group, all iconic, all worth a read 📖

and that's the whole page, no cap 🎀 This was Linux man-pages 6.20, dated 2025-12-02 — from the IPV6_RECVERR(2const) page itself. tysm for reading, go set some socket options, slay 💖✨🦋
