security_socket_getsockname(9)

💅 security_socket_getsockname(9) — the kernel API manual, bestie edition 🎀

okay so picture this: you're deep in the Kernel API Manual (that's the manual this page lives in, mwah) and you just want to know if peeking at a socket's local address is allowed. That's literally this whole page. Let's go ✨

---

🌸 NAME 🌸

security_socket_getsockname — the little vibe-check that asks "bestie, are you allowed to read this socket's address?" 👀

---

🦋 SYNOPSIS 🦋

int security_socket_getsockname (struct socket *sock );

---

⭐ ARGUMENTS ⭐

• sock — the socket. that's it. that's the whole argument. a socket, your socket, the socket in question 💖

---

🔥 DESCRIPTION 🔥

So here's the tea: this function checks permission before reading the local address (name) of the socket object. Think of it as the bouncer at the club door of your socket's identity — it looks at the socket, decides whether your reading of that local name is cool, and that's the entire job. no cap. 🫶

ngl, it's a permission check, not a data-returner. it doesn't hand you the address — it just decides whether you're allowed to go get it.

---

💀 RETURN 💀

Returns 0 if permission is granted. periodt. that's the only documented return value on this page 💅

and that's the whole page bestie!! you read all of it, i'm so proud 🥹 the source is ./security, dated October 2026, and this cutie lives in the Kernel API Manual as security_socket_getsockname(9). go forth and check those socket perms responsibly 💜✨
