🌈 NAME 🌈

snd_soc_card_jack_new — Create a new jack without pins 💅

like, no pins. none. zero. a pinless king 👑

---

🦋 SYNOPSIS 🦋

int snd_soc_card_jack_new (struct snd_soc_card *card , const char *id ,
       int type , struct snd_soc_jack *jack );

that's the whole signature, copy it exactly bestie, don't get creative with it fr fr ✨

---

💖 ARGUMENTS 💖

• card — the ASoC card, your main character 🃏
• id — an identifying string for this jack, so like, a name tag but for a jack 🏷️
• type — a bitmask of enum snd_jack_type values that can be detected by this jack 👀 (bitmask!! not just one value!! respect the bitmask!!)
• jack — the structure to use for the jack, this is where the magic gets stored 🫶

---

👑 DESCRIPTION 👑

Creates a new jack object without pins ✨ that's literally the whole thing. no pins, no problem.

🚨 important side quest: if you're planning to add pins later, you should use snd_soc_card_jack_new_pins instead, with 0 as the num_pins argument. don't come for me, that's just what the docs say 💀

Returns zero if successful, or a negative error code on failure — so like, if you get a negative number back, that's not a slay, that's a vibe check failed 😭 On success, jack will be initialised 💜
