snd_card_file_remove(9)

💅 snd_card_file_remove(9) — the Kernel API Manual, bestie ✨

Okay so this is snd_card_file_remove(9), straight out of the Kernel API Manual — and it's genuinely one of those tiny cleanup functions that keeps the whole sound subsystem from falling apart, no cap. Let's get into it 🎀

🌸 NAME 🌸

snd_card_file_remove — literally the "remove the file from the file list" girlie. That's her whole job. 💖

✨ SYNOPSIS ✨

int snd_card_file_remove (struct snd_card *card , struct file *file );

🦋 ARGUMENTS 🦋

  • card — the soundcard structure 🌈 (your main character, the card itself)
  • file — the file pointer, aka the file that's about to get politely escorted off the list 💅

💜 DESCRIPTION 💜

So basically this function removes the file that was formerly added to the card via the snd_card_file_add function. Think of it as the un-add. The ✨cleanup era✨. 🧚

And here's the dramatic part, bestie — if all files are removed and snd_card_free_when_closed was called beforehand, it goes ahead and processes the pending release of resources. So it's not just tidying up its own little corner, it's lowkey the one who finally lets the card go when the last file dips out 🫶

Fr fr, this is the close-out moment. Last file leaves → resources get released. Very "the way that she closed the door behind her" energy. 🚪✨

⭐ RETURN ⭐

Zero, or a negative error code. That's it, that's the whole scale — 0 is the slay case, negative means something went sideways 😭

Cute little sign-off: this one lives under ./sound/core in the Kernel API Manual, dated October 2026, and it goes by snd_card_file_remove(9). Periodt. 💅🎀
