💖 nng_msg_dup(3) — NNG Reference Manual 💖

okay bestie, gather round, because this one is literally the dupe button for your messages. it's nng_msg_dup, and yes, she lives in the NNG Reference Manual, and yes, she is giving copy-paste main character energy. ✨

🌸 NAME 🌸

nng_msg_dup — duplicate a message 🫶

✨ SYNOPSIS ✨

#include <nng/nng.h>

int nng_msg_dup(nng_msg **dup, nng_msg_t *orig);

💅 DESCRIPTION 💅

so here's the tea: nng_msg_dup() makes a duplicate of the original message orig, and saves the result in the location pointed by dup.

the actual message body and header content is copied — like, fully copied, no shortcuts, no cap. 🎀

but listen. the duplicate may contain a different amount of unused space than the original message. not a bug, just how she is. don't come for her. 💀

🌈 RETURN VALUES 🌈

this function returns 0 on success, and non-zero otherwise. that's it, that's the vibe check. 👑

💜 ERRORS 💜

  • NNG_ENOMEM — Insufficient free memory exists to duplicate a message. 😭 bestie the memory said no and honestly we have to respect it.
