led_blink_set_nosleep(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual — this one's about led_blink_set_nosleep, and yes the name is a whole mouthful but it's literally just "make the LED blink, but do NOT go to sleep on me." 🫶

✨ NAME ✨

led_blink_set_nosleep — set blinking, guaranteed to not sleep 🌸

⚡ SYNOPSIS ⚡

void led_blink_set_nosleep (struct led_classdev *led_cdev , unsigned
long delay_on , unsigned long delay_off );

🎀 ARGUMENTS 🎀

  • led_cdev — the LED you're about to start blinking 👑 this is the diva that gets the glow-up
  • delay_on — how long it stays on, in ms ⏱️
  • delay_off — how long it stays off, in ms 😴 (the manpage literally says "ble off" and honestly? iconic typo, we're keeping the energy 💅)

🦋 DESCRIPTION 🦋

This function makes the LED blink and it is guaranteed to not sleep ✨ like, no napping, no "brb in a sec", it just does the thing. 🏃‍♀️💨

Otherwise it's the exact same as led_blink_set — so if you want the details, go read led_blink_set, it's giving the same vibe, just with the no-sleep promise attached 💖

lowkey the whole point: you're probably in a context where sleeping is a no-no, and this function respects that. periodt. 🔥
