💅 ipw2100_set_key — a Kernel API Manual moment ✨

okay so real talk, bestie, this is a page from the Kernel API Manual and it's about one little function: ipw2100_set_key. she's not glamorous, she's not famous, but she is the one who actually pushes your WEP key down the wire, and honestly? respect. 🫶

✨ NAME ✨

ipw2100_set_key — Set a the wep key

(no, we are not fixing the "a the", that's part of her whole thing, it's iconic, leave her alone 😭)

---

🌸 SYNOPSIS 🌸

int ipw2100_set_key (struct ipw2100_priv *priv , int idx , char *key ,
       int len , int batch_mode );

---

🎀 ARGUMENTS 🎀

• priv — the struct we're working on, aka the whole vibe of the device, she's the main character here
• idx — which key we wanna set, like, the index, the slot, the little numbered drawer 💅
• key — a ptr to the key data we're setting, yes it's literally the key, no it doesn't open a door
• len — the length of the buffer sitting at key, pls keep these two in sync bestie, they're a package deal
• batch_mode — FIXME perform the operation in batch mode, not disabling the device. (yes there's a literal FIXME in the source, we're all just living like this 🙈)

---

🦋 DESCRIPTION 🦋

lowkey simple: returns 0 if OK, < 0 errno code on error. no cap. ⭐

and what does she actually do? she fills out a command structure with the new wep key, the length and the index, and then sends it down the wire. that's it. that's the whole flex. 💖

Kernel file ./drivers/net/wireless/intel/ipw2x00/ipw2100.c — go read the source, iykyk, the source is always right 👑

fr fr: if this thing errors out on you it hands back a negative errno code, so don't come for me, come for the errno. 😭

okay that's the whole page and I'm obsessed with how short it is honestly. this diva lives at ./drivers/net/wireless/intel/i... (the footer got a little truncated, she's mysterious like that 🧚) and she's dated October 2026 so she's literally from the future. periodt. 💜🌸✨
