💅 sdca_asoc_count_component(9) — the kernel API glow-up

okay so bestie, welcome to sdca_asoc_count_component(9). yes that's the whole name, it's long, it's giving "my password is my birthday" energy, but we love her. this is a kernel API manual page and honestly? it ate. let's get into it. 🎀

✨ NAME ✨

sdca_asoc_count_component — literally just counts the various component parts. that's it. that's the whole job. she's the friend who does the headcount before you get on the bus. 🚌💖

---

✨ SYNOPSIS ✨

int sdca_asoc_count_component (struct device *dev , struct
       sdca_function_data *function , int *num_widgets , int *num_routes , int
       *num_controls , int *num_dais );

look at all those pointers. so many little outputs. very main character signature honestly. 💅

---

✨ ARGUMENTS ✨

• dev — Pointer to the device against which allocations will be done. so like, the device that's paying for all the memory. the sugar mama of the operation. 💸
• function — Pointer to the Function information. capital-F Function, important vibes, she's not just any function. 🌟
• num_widgets — Output integer pointer, will be filled with the required number of DAPM widgets for the Function. widgets!! like little DAPM lego bricks. 🧱✨
• num_routes — Output integer pointer, will be filled with the required number of DAPM routes for the Function. the roads the audio takes. scenic route core. 🛣️
• num_controls — Output integer pointer, will be filled with the required number of ALSA controls for the Function. all the knobs and sliders bestie, every single one. 🎛️
• num_dais — Output integer pointer, will be filled with the required number of ASoC DAIs for the Function. plural! more than one! we love a plural. 👑

✨ DESCRIPTION ✨

okay so real talk: this function counts various things within the SDCA Function, fr fr. and why, you ask? because the calling driver needs to allocate appropriate space before calling the appropriate population functions. it's the pre-game. you gotta know how many chairs to set up before the guests arrive, iykyk. 🪑

she does not populate. she does not build. she just counts, hands you the numbers, and says "you're welcome bestie." the actual populate squad gets called afterward. that's their moment, not hers. humble queen. 🙇‍♀️

---

✨ RETURN ✨

Returns zero on success, and a negative error code on failure. so if you get 0, slay, you ate, no notes. if you get negative? not slay. check yourself. 😭

ngl bestie, if you're here you're probably writing kernel audio code, which honestly is such a flex. go off. 💅✨
