✨ vga_switcheroo_process_delayed_switch ✨

okay bestie, welcome to the vga_switcheroo_process_delayed_switch page 💅 this one lives in the Kernel API Manual, and it's literally the "did you forget to do the thing?" helper of the graphics-switching world 🦋

---

🌸 NAME 🌸

vga_switcheroo_process_delayed_switch — helper for delayed switching 🎀

---

💖 SYNOPSIS 💖

int vga_switcheroo_process_delayed_switch (void );

---

🧚 ARGUMENTS 🧚

• void — no arguments, bestie. none. zero. nada. it takes nothing 🙈 and honestly? iconic of it.

---

🔥 DESCRIPTION 🔥

So here's the tea ☕ — this function processes a delayed switch if one is pending. that's it. that's the whole vibe check. if there's a delayed switch sitting around waiting, this is the function that goes "okay girl, let's get you processed" 💅✨

if nothing's pending? congrats, it's got nothing to do. see the RETURN section for how that goes 👀

---

🌈 RETURN 🌈

• 0 on success 🎉 slay.
• -EINVAL if there's no delayed switch pending, if the client has unregistered in the meantime, or if there are other clients blocking the switch 😭💀 — multiple reasons, all of them valid, all of them giving "not right now bestie".

also important: if the actual switch fails, an error is reported and 0 is returned 🔥 like, the switch didn't work, but this function still hands you back 0. so don't just trust the 0 blindly, iykyk 🫶
