set_wiphy_dev(9)

💖 set_wiphy_dev(9) 💖

okay so this is from the Kernel API Manual bestie, section 9 — the driver-dev chapter of the kernel lore. it's a tiny little function but it's doing Real Work, so let's get into it 🫶

---

✨ NAME ✨

set_wiphy_dev — sets the device pointer for a wiphy, that's literally it, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

void set_wiphy_dev (struct wiphy *wiphy , struct device *dev );

returns nothing (void, so don't go looking for a return value, it's giving minimalism) and takes exactly two args. periodt.

---

🎀 ARGUMENTS 🎀

• wiphy — the struct wiphy whose device you're binding. this is the one getting a new parent, main character energy 👑
• dev — the struct device you're parenting it to. this is the new parent in question, no cap 🦋

---

that's part 1, there's more coming so don't go anywhere 💜

💖 SEE ALSO 💖

okay bestie, buckle up, because this section is basically the entire cfg80211 cinematic universe. Everything here lives in the kernel file ./include/net/cfg80211.h, and the tour starts with Introduction(9). After that it's just...... the whole cast list 💀, all of them (9) pages, all of them listed below in exactly the order the original gives them. No skipping, no summarising, we are reading the whole guest list. iykyk.
