💖 brcmf_apsta_add_vif(9) 💖

okay so bestie, welcome to the Kernel API Manual — specifically the page for brcmf_apsta_add_vif, and ngl this one is a serve. It's a little function that goes and makes you a brand new virtual interface, either AP or STA. iconic behaviour, honestly.

---

✨ NAME ✨

brcmf_apsta_add_vif — create a new AP or STA virtual interface 🫶

---

🌸 SYNOPSIS 🌸

struct wireless_dev * brcmf_apsta_add_vif (struct wiphy *wiphy , const
       char *name , struct vif_params *params , enum nl80211_iftype type );

yes that's the whole thing, copy it exactly, don't @ me 💅

---

🦋 ARGUMENTS 🦋

• wiphy — the wiphy device that your new interface is gonna belong to. like, its home base 🏠
• name — what you're naming the new interface. pick something cute.
• params — this is where the mac address for your AP or STA device lives 👀
• type — the interface type. the whole AP-vs-STA of it all.

---

🔥 RETURN 🔥

on success you get a pointer to the shiny new vif ✨ — but if it goes sideways you get ERR_PTR(-errno) instead. no cap, always check that one 😭

fr fr, peek at the return value before you go dereferencing anything. ERR_PTR(-errno) is not a real pointer and it will ruin your whole day 💀
