💅 sdca_asoc_populate_controls 💅

okay bestie, welcome to the Kernel API Manual page for sdca_asoc_populate_controls(9) — yes that's the whole name, yes it's a mouthful, no we're not shortening it, it's iconic as is. 🎀

✨ NAME ✨

sdca_asoc_populate_controls — literally fills in an array of ALSA controls for a Function. that's the whole vibe. no cap. 🦋

🌸 SYNOPSIS 🌸

int sdca_asoc_populate_controls (struct device *dev , struct
sdca_function_data *function , struct snd_kcontrol_new *kctl );

three args, one int back, that's the whole situation. 💖

🎀 ARGUMENTS 🎀

  • dev — pointer to the device that allocations get done against. like, this is the device your memory comes from, so be nice to it. 🙈
  • function — pointer to the Function information. the actual SDCA Function we're pulling info about, bestie. 👑
  • kctl — array of ALSA controls that's gonna get populated. this is the container you're filling, so bring a good one. ✨

💜 DESCRIPTION 💜

so what this function does: it populates an array of ALSA controls from the DisCo information for a particular SDCA Function. like it takes the DisCo info and turns it into actual ALSA control entries. 🧚

and listen — the usual flow, iykyk: typically, snd_soc_asoc_count_component will be used to allocate an appropriately sized array before calling this function. so you count first, then you populate. count then populate. that's the order. fr fr. 🔥

⭐ RETURN ⭐

returns zero on success, and a negative error code on failure. classic. zero = slay, negative = not slay. 💀
