NNG_PUSH_OPEN(3)

✨ NNG_PUSH_OPEN(3) ✨

okay bestie, welcome to the NNG Reference Manual 💖 this is the page about making a push socket, and it's genuinely not that deep — two functions, both of them little baby socket factories. let's get into it 🫶

---

🌸 NAME 🌸

nng_push_open — create push socket ✨

---

🎀 SYNOPSIS 🎀

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

int nng_push0_open(nng_socket *s);

int nng_push0_open_raw(nng_socket *s);

---

🦋 DESCRIPTION 🦋

so, two functions, both of them hand you a socket:

• nng_push0_open() — makes a push version 0 socket and drops it right where s is pointing at 💅
• nng_push0_open_raw() — same deal, push version 0 socket, except this one is in raw mode, and it also lands at the location s points to 🌈

that's it. that's the whole description. iconic honestly, no notes ✨

---

💜 RETURN VALUES 💜

both of these return 0 when it works out, and non-zero when it does not 😭 like, any non-zero, they're not being specific about it

---

🔥 ERRORS 🔥

• NNG_ENOMEM — not enough memory available, the vibes are broke, there is simply no room 💀
• NNG_ENOTSUP — the protocol is not supported 🙈
