snd_hda_jac...ble_callback(9)

✨ NAME ✨

okay bestie, welcome to the Kernel API Manual entry for snd_hda_jac...ble_callback(9) — aka snd_hda_jack_detect_enable_callback. the NAME section is literally “enable the jack-detection,” and honestly? iconic. 💅

🎀 SYNOPSIS 🎀

here’s the signature, bestie — copy it exactly:

struct hda_jack_callback * snd_hda_jack_detect_enable_callback (struct
hda_codec *codec , hda_nid_t nid , hda_jack_callback_fn cb );

🧚 ARGUMENTS 🧚

• codec — the HDA codec. that’s the whole vibe. 🎧
• nid — the pin NID to enable. go off, pin. 📌
• cb — the callback function to register. yep, register her. 📲

💖 DESCRIPTION 💖

okay so here’s the important part: in the case of error, the return value will be a pointer embedded with errno. 😭 do not ignore that. check and handle the return value appropriately with standard macros such as IS_ERR and PTR_ERR. that’s the whole safety briefing, bestie, and it ate. 🔥
