NNG_MSG_FREE(3)

💖 NAME 💖

nng_msg_free — free a message, bestie. that's it. that's the whole job. 🫶

---

🎀 SYNOPSIS 🎀

#include <nng/nng.h>

void nng_msg_free(nng_msg *msg);

like yes queen, one line of code, zero drama ✨

---

🌸 DESCRIPTION 🌸

okay so, you know how you made a message with nng_msg_alloc(3) and it was everything, main character energy, holding all your beautiful little bytes? 🦋 well bestie, every icon needs a graceful exit.

The nng_msg_free() function deallocates the message msg entirely. not partially. not "mostly". entirely. the whole thing. the entire message. gone. released. returned to the void. 💀

"entirely" is doing heavy lifting there and I need you to feel that. this isn't a gentle trim, it's a full send-off.

no cap: once it's freed, that message is NOT coming back. don't touch msg afterwards. that's giving use-after-free and that is not the vibe. 🙈

---

👑 RETURN VALUES 👑

None. she returns nothing. no value, no receipt, no goodbye text, just vibes and a chunk of memory politely handed back. 💅

---

💀 ERRORS 💀

None. literally cannot fail. cannot error. this function simply ate and left no crumbs. 🔥
