pm_save_wakeup_count(9)

💾 NAME 💾

okay so bestie, welcome to pm_save_wakeup_count(9) — that's the title, and it's from the Kernel API Manual 🫶. In one breath: it saves the current number of registered wakeup events. That's the whole main-character job, and it's lowkey important, fr fr.

✨ SYNOPSIS ✨

bool pm_save_wakeup_count (unsigned int count );

🎀 ARGUMENTS 🎀

• count — the value to compare with the current number of registered wakeup events. yes bestie, it's literally just the number that has to line up 💅.

🌸 DESCRIPTION 🌸

okay so here's the tea ☕: if count is equal to the current number of registered wakeup events and the current number of wakeup events being processed is zero, then it stores count as the old number of registered wakeup events for pm_check_wakeup_events, enables wakeup events detection, and returns 'true'. slay, iconic, the function ate 🔥.

otherwise? it disables wakeup events detection and returns 'false'. not me getting rejected by the vibe check 😭 — both conditions have to hit, periodt.
