💅 pvr_kccb_is_idle — Kernel API Manual, section 9 ✨

okay bestie, so this one is from the Kernel API Manual (section 9, kernel-space vibes only 💜) and it's genuinely the simplest little icon in the whole KCCB friend group. no cap.

🎀 NAME 🎀

pvr_kccb_is_idle — literally just tells you whether the device's KCCB is idle or not. that's it. that's the whole job. and she does it flawlessly. 👑

🦋 SYNOPSIS 🦋

bool pvr_kccb_is_idle (struct pvr_device *pvr_dev );

🌸 ARGUMENTS 🌸

  • pvr_dev — the device pointer, aka the little handle to the device you're asking about. hand her the device, she'll tell you the vibe. 🫶

⭐ RETURN ⭐

she gives you back a bool, and here's the tea:

  • true if the KCCB is idle (it contains no commands at all — empty, quiet, at peace 🧘‍♀️), or
  • false if the KCCB contains pending commands (bestie there is work in there, it is not idle, do not @ her 😭).
