💅 snd_soc_jack...ier_register(9) 💅

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, no I will not be shortening it, it's iconic ✨ this one's about snd_soc_jack_notifier_register, and it's a whole vibe.

🌸 NAME 🌸

snd_soc_jack_notifier_register — register a notifier for jack status 🎀

🦋 SYNOPSIS 🦋

void snd_soc_jack_notifier_register (struct snd_soc_jack *jack , struct
notifier_block *nb );

like, that's the whole signature, copy it exactly pls, don't be weird about it 💖

✨ ARGUMENTS ✨

  • jack — the ASoC jack 🎧 that's the one we're watching, main character energy fr
  • nb — the notifier block to register 📝 like, this is the thing that gets pinged

🫶 DESCRIPTION 🫶

okay so here's the tea ☕ — you call this to register for notification of the current status of the jack. that's it, that's the gig 💅

⚠️ no cap, important: it is not possible to report additional jack events in the callback from the notifier. so don't try it, bestie, it's not gonna slay, it's just gonna not work 😭

what is it actually for? it's intended to support applications such as enabling electrical detection only when a mechanical detection event has occurred 🔌⚡ like, it's the "hey something mechanically happened, now you may turn on your little electrical detection thing" hook. lowkey genius, honestly 👑
