NNG_MSG_BODY(3)

✨ NNG_MSG_BODY(3) ✨

okay bestie, welcome to the NNG Reference Manual 💖 this one's a lil baby page but it's important, trust.

---

🌸 NAME 🌸

nng_msg_body — return message body

---

🎀 SYNOPSIS 🎀

#include <nng/nng.h>

void *nng_msg_body(nng_msg *msg);

---

🦋 DESCRIPTION 🦋

so nng_msg_body() gives you a pointer to the start of the body content of the message msg. that's it. that's the whole vibe. she's simple, she's straightforward, she's giving ✨pointer to the goods✨.

⚠️ IMPORTANT NOTE, NO CAP ⚠️ the value you get back gets invalidated the second you call any function that modifies the message itself. like, it's so over. the culprits are nng_msg_free(), nng_msg_realloc(), and any of the nng_msg_trim(), nng_msg_chop(), nng_msg_append(), or nng_msg_insert() variants. so if you're holding onto that pointer and then you trim or append or whatever — poof, it's stale, it's expired, it's not the moment anymore. 😭

---

💅 RETURN VALUES 💅

a pointer to the start of the message body. periodt.

---

🫶 ERRORS 🫶

None. literally zero. she doesn't miss. 💀
