cfg80211_ven...d_get_sender(9)

📦 version 7.3.1, in nixpkgs unstable

✨ cfg80211_vendor_cmd_get_sender(9) ✨

okay so bestie, welcome to the kernel API manual for cfg80211_vendor_cmd_get_sender 💅 this one is lowkey iconic because it's exactly what it says on the tin — no cap, no plot twists, just a tiny little helper doing its one job beautifully 🎀

🌸 NAME 🌸

cfg80211_vendor_cmd_get_sender — get the current sender netlink ID

like... that's it. that's the whole vibe. it gets the sender. the netlink ID of the sender. fr fr 💖

🦋 SYNOPSIS 🦋

unsigned int cfg80211_vendor_cmd_get_sender (struct wiphy *wiphy );

so the return type is unsigned int (yes, an unsigned int, not an int, not a size_t, don't come for me) and it takes exactly one argument: a struct wiphy * called wiphy ✨ there's that trailing space before the closing paren in the original signature and we're keeping it because character-for-character is the assignment, periodt 🫶

🎀 ARGUMENTS 🎀

  • wiphy — the wiphy 💖 that's the entire description. the wiphy. the one and only. she's a struct wiphy * and she's the wiphy and we love her for it 🧚

⭐ RETURN ⭐

returns the current netlink port ID in a vendor command handler 🌈

that's the whole return contract, bestie — the current netlink port ID, and specifically in a vendor command handler, so don't go expecting this to be meaningful outside of that context, iykyk 👑

💜 CONTEXT 💜

may only be called from a vendor command handler 🚨

this is a hard restriction, not a suggestion, not a soft guideline, not a "whatever feels right" situation 😭 only. from. a. vendor. command. handler. that's the vibe check and if you fail it, that's on you bestie 💀

more parts incoming, don't go anywhere 🌸🦋💅

okay so the SEE ALSO list continues, and bestie it is LONG — but every one of these is a whole vibe and you're gonna want them bookmarked. no skimming, i'm watching you 👀

okay that's the first chunk, hydration check 🍓 drink some water, then keep scrolling:

we're in the NAN era now and honestly? iconic ✨ not me getting attached to a function list:

final stretch bestie, we're so close, main character energy only 💅:

and that's the whole list!! you made it, i'm so proud 😭🫶 go read a few of these for fun, it's giving study buddy era.

okay and before you close the tab: this page came out of ./include/net, dated October 2026, and it's the cfg80211_ven...d_get_sender(9) page — so if you ever need to cite it or find it again, that's your receipt, bestie. mwah, go touch some grass (after you finish the docs) 🌸✨
