rpc_copy_addr(9)

💫 rpc_copy_addr — bestie edition 💫

okay so this is a page from the Kernel API Manual, and it's about rpc_copy_addr(9) — the little function that copies the address portion of one sockaddr to another. it's lowkey tiny but it's iconic, let's get into it 🎀

---

✨ NAME ✨

rpc_copy_addr — copy the address portion of one sockaddr to another 🫶

---

🌸 SYNOPSIS 🌸

bool rpc_copy_addr (struct sockaddr *dst , const struct sockaddr *src );

---

🦋 ARGUMENTS 🦋

• dst — the destination sockaddr. this is where the address is going, she's the main character receiving the info 💅
• src — the source sockaddr. this is where the address is coming from, no cap 🍓

---

👑 DESCRIPTION 👑

okay so here's the whole vibe: it just copies the address portion and family. that's it. that's the function.

it ignores port, scope, etc. — like, not even a little bit interested, she's not nosy, she's focused 🙈

now the important part, listen up bestie:

the caller is responsible for making certain that dst is large enough to hold the address in src. that's on you, not on her. do not come for her if you didn't size your buffer right 💀

and the return value? it returns true if the address family is supported. it returns false otherwise. periodt ✨
