NNG_MSG_CLEAR(3)

✨ NNG_MSG_CLEAR ✨

okay bestie, welcome to the NNG Reference Manual 💖 this is NNG_MSG_CLEAR(3) and it is genuinely the shortest lil glow-up in the whole library. no cap.

---

🌸 NAME 🌸

nng_msg_clear — clear message body content

like, the whole personality of this function is "make the body empty." that's it. that's the vibe. 🎀

---

🦋 SYNOPSIS 🦋

#include <nng/nng.h>

void nng_msg_clear(nng_msg *msg);

periodt. look at her. returning void, taking one pointer, zero drama. 💅

---

💜 DESCRIPTION 💜

The nng_msg_clear() function resets the body length of msg to zero. ✨

that's literally it, and honestly? iconic. your message keeps being a message, it just doesn't have any body content anymore. the length goes bye-bye, hits zero, done. nothing else about msg gets touched — we're only talking about the body length, so don't go reading into it. 🙈

---

🫶 RETURN VALUES 🫶

None.

she gives you nothing back because she has nothing to give back. no return value, no notes, no follow-up. the way that a void function just… exists. 😭

---

💀 ERRORS 💀

None.

can't fail if you never try ✨ — no error states, no errno behaviour, nothing to check. just call it and go about your day, bestie. 👑
