NNG_REP_OPEN(3)

💖 NNG_REP_OPEN(3) 💖

okay bestie, gather round, because we're opening a whole reply socket and it's about to be iconic. this is page NNG_REP_OPEN(3) from the NNG Reference Manual, and no cap, it's short and sweet — but every single detail matters, so let's not skip a crumb. ✨

---

🌸 NAME 🌸

nng_rep_open — create rep socket

---

🎀 SYNOPSIS 🎀

#include <nng/nng.h>
#include <nng/protocol/reqrep0/rep.h>

int nng_rep0_open(nng_socket *s);

int nng_rep0_open_raw(nng_socket *);

---

🦋 DESCRIPTION 🦋

so the way this works is adorable actually:

nng_rep0_open() creates a rep version 0 socket and hands it back to you at the location pointed to by s. that's it, that's the whole vibe. 💅

and then there's nng_rep0_open_raw(), which does the same little dance but makes a rep version 0 socket in raw mode, returning it at the location pointed to by s. raw mode said "i'm the main character, i do my own framing." 👑

---

⭐ RETURN VALUES ⭐

both of these functions return 0 on success, and non-zero otherwise. classic. lowkey zero is the slay number here. 🫶

💀 ERRORS 💀

• NNG_ENOMEM — not enough memory available, like when the group chat is full and your pics won't send. insufficient memory, bestie. 😭
• NNG_ENOTSUP — the protocol is not supported. it's giving "this feature isn't in your build," and we move on. 🙈
