futex_wake(9)

📦 version 7.3.1, in nixpkgs unstable

💖 futex_wake(9) 💖

okay bestie, welcome to the futex_wake(9) page — straight out of the Kernel API Manual and honestly? it's giving "short but mighty." ✨

🌸 NAME 🌸

futex_wake — wake one or more tasks blocked on uaddr

like, it literally goes and taps your sleeping tasks on the shoulder and is like "girl, wake up" 💅

🦋 SYNOPSIS 🦋

int futex_wake (futex_t *uaddr , int nr_wake , int opflags );

yes that's the whole thing. no cap. 🎀

✨ ARGUMENTS ✨

  • uaddr — the manpage is out here literally saying -- undescribed -- 😭 so that's exactly what we're passing along, no invented lore, we don't make things up in this house 🫶
  • nr_wake — wake up to this many tasks. that's it. that's the number. set your limit, bestie 💫
  • opflags — also -- undescribed -- 🙈 again, not gonna pretend otherwise. the docs said nothing so I say nothing. iykyk.

👑 SEE ALSO 👑

  • Kernel file ./tools/testing/selftests/futex/include/futextest.h — the source file, go look at it, it's right there ⭐

and then the whole futex friend group, because obviously they all roll together:

the way that this list is literally the entire futex extended universe 💀🔥

ok but fr fr — that's genuinely every single family member, don't come for me if you were looking for more, that's what the page gave us 💜

and that's a wrap, my love 🎀 this little gem comes to you from the source ./tools/testing/selftests/fute... and it's dated October 2026 — iconic, timeless, periodt. 🌈💖
