💅 qeth_l2_pnso(9) 💅

okay so bestie, welcome to the qeth_l2_pnso page — it lives in the Kernel API Manual and it's literally about doing a network subchannel operation. yes that's the whole NAME section, she's short and she knows it ✨

✨ SYNOPSIS ✨

int qeth_l2_pnso (struct qeth_card *card , u8 oc , int cnc , void
(*cb)(void *priv, struct chsc_pnso_naid_l2 *entry) , void *priv );

like, look at her. five things go in, an int comes out. no cap that's the whole vibe 🫶

🎀 ARGUMENTS 🎀

  • card — a qeth_card structure pointer, aka the main character of this whole function 💳
  • oc — the Operation Code (u8, tiny but mighty) ⚙️
  • cnc — Boolean Change-Notification Control, so a yes/no situation fr fr 🔔
  • cb — the callback function, and she gets executed for each and every element of the address list. every single one. she's booked and busy 😭
  • priv — a pointer that gets passed along to the callback function, like a little note you hand your friend to give to the next friend 🫶

🌸 DESCRIPTION 🌸

So what does she actually do? She collects network information into a network address list, then calls the callback function for every entry in that list. iconic behavior honestly 👑

And here's the extra little plot twist: if "change-notification-control" is set, further changes in the address list will be reported via the IPA command. so she doesn't just leave after the first hangout — she keeps you in the loop 🔥
