NNG_MSG_SET_PIPE(3)

💖 nng_msg_set_pipe — set pipe for message 💖

okay bestie, welcome to the NNG Reference Manual, page NNG_MSG_SET_PIPE(3). sit down, grab a strawberry 🍓, and let's talk about telling a message exactly which pipe it should slide out of.

---

✨ SYNOPSIS ✨

#include <nng/nng.h>

void nng_msg_set_pipe(nng_msg *msg, nng_pipe p);

like, that's it. one line. no return value, no drama. 🎀

---

🦋 DESCRIPTION 🦋

So nng_msg_set_pipe() sets the pipe associated with message m to p. yep, that's the whole job and it ate. 💅

This is most often useful when you're working with protocols that support directing a message to a specific peer. like, you've got a message and you're like "no babe, you go to that one" — that's this. 🌸

for example, the pair version 1 protocol can do this when NNG_OPT_PAIR1_POLY mode is set. iconic behavior tbh.

⚠️ Note: Not all protocols support overriding the destination pipe. so like… vibe check your protocol first, bestie. don't just assume. 🙈

---

💜 RETURN VALUES 💜

None.

(yeah. nothing. it's giving mysterious. the function simply does the thing and returns into the void. ✨)

---

🌈 ERRORS 🌈

None.

no errors, no tears, no errno situations. we love a low-maintenance king. 👑
