snd_hdac_is_...orted_format(9)

🌸 snd_hdac_is_supported_format(9) — Kernel API Manual, but make it cute 🌸

okay so bestie, this is a page from the Kernel API Manual and the function is literally called snd_hdac_is_supported_format. yes the title in the header is all squished up like snd_hdac_is_...orted_format(9) (they truncated it, iconic behaviour honestly), but the actual name is the full thing. let's get into it 💅

✨ NAME ✨

snd_hdac_is_supported_format — the vibe check for a format. it checks the validity of the format, no cap 🫶

---

🎀 SYNOPSIS 🎀

bool snd_hdac_is_supported_format (struct hdac_device *codec , hda_nid_t
nid , unsigned int format );

like, that's the whole signature. she's a bool, she takes three things, she's got main character energy 💖

---

🦋 ARGUMENTS 🦋

• codec — the codec object. the whole device situation, your girl's home base ✨
• nid — the NID to check. that's the node ID we're looking at, iykyk 🎯
• format — the HD-audio format value to check. the actual format number we're putting under the microscope 🔍

---

💜 DESCRIPTION 💜

okay so here's the whole thing: this function checks whether the given node supports the format value. that's it, that's the tea ☕

she returns true if it's supported, and false if not. simple as that, periodt 💅
