wait_event_...sive_timeout(9)

🌸 NAME 🌸

okay so bestie, this is the Kernel API Manual page for wait_event_idle_exclusive_timeout — header shorthand wait_event_...sive_timeout(9) — and it is literally the “sleep without load until a condition becomes true or a timeout elapses” girlie. no cap 💖

---

✨ SYNOPSIS ✨

wait_event_idle_exclusive_timeout (wq_head , condition , timeout );

copy it exactly, spaces and all — she is precise 💅

---

🦋 ARGUMENTS 🦋

• wq_head — the waitqueue to wait on. the main-character waitqueue, iykyk 🎀
• condition — a C expression for the event to wait for. This is the tiny vibe check the function keeps running ✨
• timeout — timeout, in jiffies. jiffies, bestie, not seconds ⏳

---

💜 DESCRIPTION 💜

The process is put to sleep (TASK_IDLE) until the condition evaluates to true. The condition is checked each time the waitqueue wq_head is woken up.

The process is put on the wait queue with the WQ_FLAG_EXCLUSIVE flag set — thus if other processes wait on the same list, when this process is woken further processes are not considered. exclusive behavior, periodt 👑

wake_up has to be called after changing any variable that could change the result of the wait condition. this is required, bestie 😭

---

🌈 RETURN 🌈

• 0 if the condition evaluated to false after the timeout elapsed
• 1 if the condition evaluated to true after the timeout elapsed
• or the remaining jiffies (at least 1) if the condition evaluated to true before the timeout elapsed

three possible outcomes, bestie ⭐
