snd_ctl_find_numid(9)

🌸 NAME 🌸

okay bestie, this is snd_ctl_find_numid(9) from the Kernel API Manual 💖 and it does exactly what it says on the tin: find the control instance with the given number-id ✨

✨ SYNOPSIS ✨

struct snd_kcontrol * snd_ctl_find_numid (struct snd_card *card ,
unsigned int numid );

🎀 ARGUMENTS 🎀

• card — the card instance 💳 your main-character card, if you will
• numid — the number-id to search 🔎 like a little detective but for number-ids

💅 DESCRIPTION 💅

Finds the control instance with the given number-id from the card. No cap, that's the whole vibe 🔥

heads up bestie 🫶 note that this function takes the card->controls_rwlock lock internally, so yeah, it's doing lock stuff behind the scenes 💅

🌈 RETURN 🌈

The pointer of the instance if found, or NULL if not 🦋 that's the vibe check, fr fr.
