NNG_PUB_OPEN(3)

💅 NNG_PUB_OPEN(3) — the NNG Reference Manual, but make it cute

okay bestie, listen up, because this one is literally the doorway to being a broadcaster 👑

---

✨ NAME ✨

nng_pub_open — create pub socket 🎤

---

🌸 SYNOPSIS 🌸

#include <nng/nng.h>
#include <nng/protocol/pubsub0/pub.h>

int nng_pub0_open(nng_socket *s);

int nng_pub0_open_raw(nng_socket *s);

---

🦋 DESCRIPTION 🦋

So here's the tea, lovely. The nng_pub0_open() function creates a pub version 0</> socket and hands it back to you at the location that s points to. That's it, that's the whole vibe ✨

And the nng_pub0_open_raw() function? She creates a pub version 0 socket but in raw mode 💀 and returns it at the location pointed to by s. Yes queen, raw mode is its own whole personality, iykyk.

heads up: both of these drop the socket into whatever nng_socket *s is pointing at, so make sure s is actually pointing somewhere real, bestie. No vibes-only pointers 💖

---

🎀 RETURN VALUES 🎀

These functions return 0 on success, and non-zero otherwise. That's the whole report card. 0 = slay, anything else = not slay 😭

---

🔥 ERRORS 🔥

• NNG_ENOMEM — Insufficient memory is available. like the laptop is going through it 💀
• NNG_ENOTSUP — The protocol is not supported. she's just not available for this, no cap 🙈
