NNG_MTX_UNLOCK(3supp)

💅 NNG_MTX_UNLOCK 💅

okay so bestie, welcome to NNG_MTX_UNLOCK(3supp) from the NNG Reference Manual — this is the page about letting go of a mutex, and honestly it's giving "short but iconic." ✨

---

🌸 NAME 🌸

nng_mtx_unlock — unlock a mutex, aka the moment you finally release the vibe and let the other threads in 🫶

---

✨ SYNOPSIS ✨

#include <nng/nng.h>

void nng_mtx_unlock(nng_mtx *mtx);

like, that's it. two lines. main character energy fr fr 🎀

---

🦋 DESCRIPTION 🦋

So nng_mtx_unlock() relinquishes ownership of the mutex mtx that was previously acquired via nng_mtx_lock(). Basically: you grabbed the mic, you said your thing, now you hand the mic back. periodt. 🎤

⚠️ Important — and I'm gonna say this loud because it matters: a mutex can only be unlocked by the thread that locked it. Attempting to unlock a mutex that is not owned by the caller will result in undefined behavior. That's not a cute quirky bug, that's chaos. 💀 Not me warning you twice. Do not pass go. Do not unlock a mutex that isn't yours. iykyk 🙈

---

⭐ RETURN VALUES ⭐

None. Nothing. Nada. It's void, bestie — it does not come back with receipts. 💅

---

🌈 ERRORS 🌈

None. Zero. Zip. No error codes to check, no errno to stress about. 🧚
