resume_event(9)

💤 resume_event(9) — the kernel API manual, bestie edition ✨

Okay so real talk, we're deep in the kernel's power-management era (Kernel API Manual, section 9, if anyone's keeping score 🎀) and today's main character is resume_event. It is literally the "and now we wake up" of the suspend/resume saga. Sit down, grab a strawberry drink 🍓, and let's get into it.

---

✨ NAME ✨

resume_event — returns a "resume" message for whatever "suspend" sleep state you hand it. That's the whole vibe. Sleepy in, wakey out. 🦋

---

🌸 SYNOPSIS 🌸

pm_message_t resume_event (pm_message_t sleep_state );

That's it. One arg in, one pm_message_t out. Clean, iconic, no notes. 👑

---

🎀 ARGUMENTS 🎀

• sleep_state — a PM message that represents a sleep state. Like, the suspend side of the story. Hand it over and let the function do its thing. 💅

---

💖 DESCRIPTION 💖

Okay so here's the tea ☕: resume_event returns a PM message that represents the resume event corresponding to the given sleep_state. You bring the sleep state, it brings the matching resume message. That's the whole function, and honestly? It ate. No cap. 🔥

No side quests, no hidden behaviour, no plot twists — the description is exactly one (1) sentence of truth and we respect her for it. 🫶
