rtw_get_wps_ie(9)

💖 rtw_get_wps_ie(9) — the "where's the WPS IE bestie" hunt 💖

okay so this is a page from the Kernel API Manual, all about rtw_get_wps_ie — yes it's a mouthful, we're gonna get through it together 🫶

---

✨ NAME ✨

rtw_get_wps_ie — Search WPS IE from a series of IEs

like, you hand it a big pile of IEs and it goes digging for the WPS one 🔍💅

---

🌸 SYNOPSIS 🌸

u8 * rtw_get_wps_ie (u8 *in_ie , uint in_len , u8 *wps_ie , uint *wps_ielen );

that's the whole vibe, no cap ✨

---

🎀 ARGUMENTS 🎀

• in_ie — the address of the IEs you wanna search through. literally the starting point of the hunt, bestie 📍
• in_len — the length limit from in_ie. it's giving "don't wander past this line" 🚧
• wps_ie — if this is not NULL and a WPS IE is found, the WPS IE gets copied into the buf starting from wps_ie 💌 (yes, a little delivery service)
• wps_ielen — if this is not NULL and a WPS IE is found, it gets set to the length of the entire WPS IE. the whole thing, not just a piece 👑📏

---

⭐ RETURN ⭐

The address of the WPS IE that was found — or NULL if it wasn't 🥲

so like… check for NULL, bestie. seriously. don't just start dereferencing and hope for the best 😭
