for_each_sband_iftype_data(9)

📦 version 7.3.1, in nixpkgs unstable

💖 for_each_sband_iftype_data — the Kernel API Manual moment 💖

okay bestie, so we're in the <pink>Kernel API Manual</pink> and the function we're stanning today is for_each_sband_iftype_data(9). she's a macro, she's a loop, she's literally the group-chat admin of iftype data entries. let's get into it 🫶

✨ NAME ✨

for_each_sband_iftype_data — iterate sband iftype data entries 🦋

like, that's the whole vibe. you're walking through those entries one by one. no cap.

🌸 SYNOPSIS 🌸

for_each_sband_iftype_data (sband , i , iftd );

that's it. three little cuties in the parentheses and you're off. ✨

🎀 ARGUMENTS 🎀

  • sband — the sband whose iftype_data array to iterate 💅 this is the main character. the array lives here and you're about to scroll through it.
  • i — iterator counter 👑 she's your index, your little tracker, the one keeping count while the loop does its thing.
  • iftd — iftype data pointer to set 🌟 the loop hands you the pointer here, so this is where you'll find each entry as you go.
lowkey obsessed with how small this one is, but bestie we are not done — more parts are coming, so don't wander off 💖

✨ SEE ALSO ✨

okay bestie, before you close this tab and go touch grass, here's the entire friend group this function rolls with — every single one, no cap. it's a lot. like, a lot lot. but you got this 💅

first up, the home base file and the immediate squad:

then we get into the actions and configuration era — this is where the real ones live:

next chapter of the group chat: scanning and BSS list handling. lowkey iconic:

the wiphy family is huge, but they're all slay:

utility functions said "let us introduce ourselves":

data path helpers, aka the ones that actually move the packets:

regulatory enforcement infrastructure — the hall monitors of the group:

then the BSS handling besties keep showing up:

RFkill integration and vendor commands — very demure, very mindful:

and the final stretch — connection, roaming, and all the notification besties (no skips, periodt):

that's the whole squad, bestie. every single one accounted for. you're welcome 💖✨

Okay bestie, the guest list continues — this is the rest of the SEE ALSO crew, and honestly? It's a lot of icons in one room 💅

And that's the whole page, bestie — you made it to the end, which is honestly slay of you. 🦋

This little masterpiece lives in ./include/net, dated October 2026, and the manual itself is for_each_sband_iftype_data(9). Now go forth and iterate, icon. 💖✨
