💤 wait_for_completion_interruptible(9) 💤

okay so bestie, welcome to section 9 of the Kernel API Manual 🫶 — the part where we talk about kernel functions, and specifically about this little icon, wait_for_completion_interruptible. she's a sleeper, she's patient, she's lowkey interruptible, and honestly? she ate. periodt. 💅

✨ NAME ✨

wait_for_completion_interruptible — waits for completion of a task (w/intr) 🎀

like literally. that's her whole job. she waits. she completes. she's interruptible. no cap.

🌸 SYNOPSIS 🌸

int wait_for_completion_interruptible (struct completion *x );

that's it, that's the whole vibe check. one function, one parameter, one int coming back at you. 💖

🦋 ARGUMENTS 🦋

  • x — holds the state of this particular completion. not a general state, not a group state, this particular one. she's specific like that. 👑

🌈 DESCRIPTION 🌈

so what does she actually do? she waits for completion of a specific task to be signaled. ✨ that's the whole thing. that's the assignment.

and the headline feature, the part that makes her main character energy: she is interruptible. 🔥 meaning the wait can get interrupted instead of just sitting there forever with zero self-respect. anyway.

⭐ RETURN ⭐

  • -ERESTARTSYS — if interrupted 😭 like, something came in and said "ma'am, we need you elsewhere." it happens to the best of us.
  • 0 — if completed 💖 the happy ending. the slay. the glow-up. she waited, the task finished, everybody wins. 🎀
