tipc_sendmsg(9)

💌 tipc_sendmsg(9) — the kernel API manual, bestie edition 🎀

okay so you found the tipc_sendmsg(9) page in the Kernel API Manual, and honestly? it's a little cutie. let's get into it 💅

---

✨ NAME ✨

tipc_sendmsg — send a message in a connectionless manner 🦋

no connection, no strings, just vibes and a destination you gotta spell out yourself. periodt.

---

🌸 SYNOPSIS 🌸

int tipc_sendmsg (struct socket *sock , struct msghdr *m , size_t dsz );

look at that signature. iconic. she takes three things and she's not sorry about it 💖

---

🫶 ARGUMENTS 🫶

• sock — the socket structure, aka the whole entire main character of this function 🌟
• m — the message you wanna send, the actual payload-bearer 🧚
• dsz — how many bytes of user data you're sending. the receipts. the count. keep it accurate bestie 🔥

---

💀 DESCRIPTION 💀

so here's the tea: your message must have a destination specified explicitly. no autocorrect, no guessing, no "she'll figure it out." you say where it goes, or nothing happens 🙈

this one's used for SOCK_RDM and SOCK_DGRAM messages — the connectionless girlies — and also for 'SYN' messages on SOCK_SEQPACKET and SOCK_STREAM connections ⭐

🚨 important warning, ngl: 'SYN+' is prohibited on SOCK_STREAM. do not try it. it's not giving. it's giving error. 💀

---

🌈 RETURN 🌈

on success? she returns the number of bytes sent 💖 on failure? errno otherwise. that's it, that's the whole mood 😭
