STRUCT JACK_STATE(9)

💖 struct jack_state(9) — like, the Kernel API Manual page, bestie 💖

okay so before we even get into it: this is a page from the Kernel API Manual, and it's all about struct jack_state — the lil' data holder that keeps your jack info alive between interrupts. Yes, between them. It's giving "I hold onto the lore so you don't have to" energy. 🎀

✨ NAME ✨

struct jack_state — the Jack state structure to keep data between interrupts. That's literally its whole job, and it does it slayfully. 💅

🌸 SYNOPSIS 🌸

struct jack_state {
    struct snd_kcontrol *kctl;
    struct snd_soc_jack *jack;
    unsigned int mask;
 };

Three members, no notes. Iconic behavior, honestly. 🦋

🎀 Members 🎀

• kctl — Pointer to the ALSA control attached to this jack. That's your control hookup, bestie, pointing right at the ALSA control that belongs to this jack. 🫶
• jack — Pointer to the ASoC jack struct for this jack. Yeah it's a jack pointing at a jack, that's just how it is, don't overthink it. 🔥
• mask — Possible reported jack status bits for this jack. The full set of status bits that could get reported for this jack — the possibilities, the potential, the main character energy. 👑
