kernel_connect(9)

💫 kernel_connect(9) 💫

okay bestie, so this is a page from the Kernel API Manual and it's literally called kernel_connect — yes, the connect-a-socket situation but make it kernel space 🎀

---

✨ NAME ✨

kernel_connect — connect a socket (kernel space) 🫶

---

🌸 SYNOPSIS 🌸

int kernel_connect (struct socket *sock , struct sockaddr_unsized *addr
, int addrlen , int flags );

no cap, that's the whole signature 💅

---

🦋 ARGUMENTS 🦋

• sock — the socket itself, your main character 🫶
• addr — the address
• addrlen — how long that address is
• flags — flags (O_NONBLOCK, ...) — and yes the ... is doing a lot of work there, iykyk

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ — what kernel_connect actually does depends on what kind of socket you're dealing with, and ngl it's giving two very different vibes:

• For datagram sockets 💌 — addr is the address to which datagrams are sent by default, and it's the only address from which datagrams are received. periodt, that's the one
• For stream sockets 🌊 — it attempts to connect to addr.

and it returns 0 or an error code. that's it, that's the whole energy ✨
