iwpm_compare_sockaddr(9)

✨ iwpm_compare_sockaddr ✨

okay so bestie, welcome to iwpm_compare_sockaddr(9) — that's section 9, the Kernel API Manual, we're deep in kernel land and honestly? it's giving main character energy. this one's a little function that literally just looks at two addresses and tells you if they're the same 💅

---

🎀 NAME 🎀

iwpm_compare_sockaddr — compare two sockaddr storage structs. that's it. that's the whole job. no cap.

---

🌸 SYNOPSIS 🌸

int iwpm_compare_sockaddr (struct sockaddr_storage *a_sockaddr , struct
sockaddr_storage *b_sockaddr );

it takes two pointers, returns an int, and yes the spacing is exactly like that, don't come for me 🙈

---

🦋 ARGUMENTS 🦋

• a_sockaddr — the first sockaddr you wanna compare. your OG. the one on the left 💖
• b_sockaddr — the second sockaddr you wanna compare. the contender. the one on the right 🫶

---

💀 RETURN 💀

returns 0 if these two are holding the same ip/tcp address info. if they're not the same? it returns 1. that's the whole vibe check, no in-between, no "undefined behaviour" cliffhanger, we love a clean answer ✨

lowkey remember: 0 = match, 1 = nope. don't flip it in your head, bestie, that's how bugs are born 😭
