schedule_hrt..._range_clock(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

schedule_hrtimeout_range_clock — sleep until timeout 😴💤

okay so this is from the Kernel API Manual (yes, the Big Kernel Energy manual, we love her) and she's basically the "nap until further notice" function. periodt.

🎀 SYNOPSIS 🎀

int schedule_hrtimeout_range_clock (ktime_t *expires , u64 delta , const
       enum hrtimer_mode mode , clockid_t clock_id );

like, look at her. returns an int, takes four things, absolute icon behavior 💅

🌸 ARGUMENTS 🌸

  • expires — the timeout value, and she's a ktime_t (a pointer to one, bestie, don't forget the star ⭐)
  • delta — the slack in the expires timeout. she's a u64 up here in the signature but the manpage calls her a ktime_t, so write that down 📝
  • mode — the timer mode, const enum hrtimer_mode no cap
  • clock_id — which timer clock to be used, she's a clockid_t 🕰️

🦋 DESCRIPTION 🦋

ngl the details are literally explained in the schedule_hrtimeout_range function description, because this function is commonly used and they didn't wanna retype the whole thing 💀 so if you want the full lore, go read that one, iykyk.

🫶 SEE ALSO 🫶

kernel file ./kernel/time/sleep_timeout.c and her whole friend group:
