rtw_get_ie_ex(9)

💖 rtw_get_ie_ex — the manual page, but make it make sense 💖

okay bestie, this one's a rtw_get_ie_ex(9) kernel API page from the Kernel API Manual — and it's literally just one little function that goes hunting for a specific IE in a big pile of IEs. "Search specific IE from a series of IEs" — that's the whole NAME, no notes, she's concise. ✨

---

🎀 SYNOPSIS 🎀

u8 * rtw_get_ie_ex (u8 *in_ie , uint in_len , u8 eid , u8 *oui , u8
oui_len , u8 *ie , uint *ielen );

seven arguments, no cap. she's high-maintenance but she delivers. 💅

---

🌸 ARGUMENTS 🌸

okay so here's the whole cast, each one doing her thing:

• in_ie — the address of the IEs you wanna search. this is the pile, the whole vibe, the group chat you're scrolling through.
• in_len — the length limit starting from in_ie. basically how far down the chat you're allowed to scroll before you gotta stop. 🫶
• eid — the Element ID to match. this is the actual thing you're looking for, the main character of the search. 👑
• oui — the OUI to match. yes, another matching criterion, she's picky fr fr.
• oui_len — the OUI length. how many bytes of OUI you're matching on. that's it, that's the whole gig.
• ie — if this is not NULL and the specific IE gets found, the IE will be copied into the buf starting from the specific IE. so she's your lil delivery driver. 🚚✨
• ielen — if this is not NULL and the specific IE gets found, it'll be set to the length of the entire IE. yup, the whole thing, not a piece. 🍓

⭐ RETURN ⭐

the address of the specific IE found 💖 — or NULL if she came up empty, which, 😭, happens. vibe check failed, bestie. no IE for you.
