wakeup_source_destroy(9)

💖 wakeup_source_destroy 💖 (that's the wakeup_source_destroy(9) page, from the Kernel API Manual, bestie)

okay so picture this: you made a struct wakeup_source, and now you gotta let it go. this page is literally just the "break up era" function. nothing more, nothing less. 🦋

---

✨ SYNOPSIS ✨

void wakeup_source_destroy (struct wakeup_source *ws );

yes that's the whole signature. no return value, no drama (well, okay, it returns void, which is its own kind of drama). 💅

---

🎀 ARGUMENTS 🎀

• ws — the wakeup source you're about to destroy. that's it. that's the argument. say bye 🫶

---

🌸 DESCRIPTION 🌸

so, real talk: you use this only for wakeup source objects that were created with wakeup_source_create. like, that's the whole rule. if you made it with wakeup_source_create, then wakeup_source_destroy is your girl. match made in heaven, periodt. ✨

not me stressing the "only" — this is a pairing situation, bestie. created with wakeup_source_create → destroyed with wakeup_source_destroy. don't mix and match, i'm begging 🙈
