✨ NAME ✨

okay bestie, welcome to nng_aio_set_msg — it's from the NNG Reference Manual, section 3 of the manual pages. It sets the message for an asynchronous send. that's the whole job. she's a one-trick pony and she EATS every time 💅

🌸 SYNOPSIS 🌸

like, here's the whole entire vibe:

#include <nng/nng.h>

void nng_aio_set_msg(nng_aio *aio, nng_msg *msg);

no return value, no drama, just vibes ✨

---

💖 DESCRIPTION 💖

sooo nng_aio_set_msg() sets the message that's gonna be used for an asynchronous send operation 👑 if you wanna see the whole send situation she's feeding into, go peek at nng_send_aio().

🚨 Important, and I mean it, no cap: the nng_aio must not have an operation in progress. like, do NOT do this while she's busy. she is not multitasking and she does not want to be. wait your turn, bestie 😭

---

🎀 RETURN VALUES 🎀

None. literally nothing. she gives you silence and it's iconic for her 🌈

---

🦋 ERRORS 🦋

None. zero. no notes. flawless behaviour fr fr 💖
