NNG_PULL_OPEN(3)

✨ NNG_PULL_OPEN(3) ✨

okay bestie, welcome to the NNG Reference Manual 💖 this one is so chill, you're literally just gonna make a pull socket. that's it. that's the whole vibe. 🫶

🎀 NAME 🎀

nng_pull_open — create a pull socket

like. it opens a pull socket. the name ate, honestly, no notes. ✨

---

🦋 SYNOPSIS 🦋

#include <nng/nng.h>
#include <nng/protocol/pipeline0/pull.h>

int nng_pull0_open(nng_socket *s);

int nng_pull0_open_raw(nng_socket *s);

yes you need both includes, don't skip the second one, she's important 💅

---

🌸 DESCRIPTION 🌸

So the way this works, bestie:

• nng_pull0_open() — this one creates a pull version 0 socket and hands it back to you at the location that s points to. very "here u go queen, it's yours now" energy 👑
• nng_pull0_open_raw() — same thing, except it creates that pull version 0 socket in raw mode, and also returns it at the location pointed to by s. raw mode is the whole personality difference here, don't get it twisted. 🔥

that's literally the entire function. two doors, same hallway, one of them is raw.

---

💜 RETURN VALUES 💜

These functions return 0 on success, and non-zero otherwise. zero = slay, non-zero = we have a situation 😭

---

💀 ERRORS 💀

• NNG_ENOMEM — Insufficient memory is available. the RAM said "not today" 🙈
• NNG_ENOTSUP — The protocol is not supported. the protocol just isn't invited to the party 🍓
