suspend_enter(9)

✨ NAME ✨

okay so bestie, this is suspend_enter — and it's literally the function that makes the system enter the given sleep state. that's the whole vibe. 💤

(this one lives in the Kernel API Manual, iykyk 👑)

---

🌸 SYNOPSIS 🌸

int suspend_enter (suspend_state_t state , bool *wakeup );

like, that's it. two args, one int coming back at you. no cap. ✨

---

🎀 ARGUMENTS 🎀

• state — the system sleep state you wanna enter. that's the one, the target, the main character of this call 💅
• wakeup — a bool *, and it returns info saying the sleep state should not be re-entered. so it's a little out-param telling you "bestie, don't go back in there" 🙈

---

🦋 DESCRIPTION 🦋

This function should be called after devices have been suspended. that's the rule, that's the assignment, and the way that ordering matters is honestly iconic. devices first, then you enter the sleep state. in that order. periodt. 🔥
