💖 acpi_nhlt_en...nt_mic_count(9) 💖

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, we're in kernel-land now 🐧✨ this little page is all about acpi_nhlt_endpoint_mic_count, and it's genuinely one of the more chill functions you'll meet here. no cap.

✨ NAME ✨

acpi_nhlt_endpoint_mic_count — literally just retrieves the number of digital microphones for a PDM endpoint 🎤🦋

that's it. that's the whole job. she's focused. she's iconic. she knows exactly one thing and she does it 💅

---

🌸 SYNOPSIS 🌸

int acpi_nhlt_endpoint_mic_count (const struct acpi_nhlt_endpoint *ep );

like, look at her. int in, int out, one const struct acpi_nhlt_endpoint * argument, and she's not even gonna modify it because it's const — respectful queen behavior 👑 note the trailing space before the ) in the signature, we're keeping it exactly as written, fr fr.

---

🎀 ARGUMENTS 🎀

• ep — the endpoint you want the microphone count for 🎤 like, hand her the endpoint and she'll tell you how many mics are in there. that's the vibe check she's running.

---

🌈 RETURN 🌈

she returns a number of microphones 🎧✨

or — and this is the important part, bestie, don't skip it 😭 — an error code if an invalid endpoint is provided. so if you hand her nonsense, she's not gonna pretend, she's gonna hand you back an error code. respect.

⚠️ lowkey the whole lesson here: check your endpoint before you call, or be ready to actually handle that error code. no silent failures, no vibes-based error handling 💀
