GLUTUSELAYER(3)

💅 GLUTUSELAYER(3) — the glutUseLayer era 💅

okay bestie, so this one lives in the OpenGLUT manual, specifically in the overlays section, and it's literally the little switch that decides whether you're vibing in your normal window or in a layer. short page, big feelings. let's get into it 🫶

---

✨ NAME ✨

glutUseLayer — Allows you to switch between normal and layer mode. that's it, that's the whole job 💖

---

📚 LIBRARY 📚

OpenGLUT - overlays 🌸

---

🌈 SYNOPSIS 🌈

#include <openglut.h>

void
glutUseLayer(GLenum layer);

like, one function, one argument, very demure, very mindful 🎀

---

🦋 PARAMETERS 🦋

• layer — whether you wanna be in a layer or in the normal window. that's the whole vibe check right there.

---

👑 DESCRIPTION 👑

so by default, OpenGLUT is out here operating in "normal" mode when it comes to layers. no layer energy, just the regular window. periodt.

but if you've got a layer open and you're like "hiii i want to actually operate on the layer bestie", you must call glutUseLayer(). there is no other way in, no secret shortcut, no main character backdoor. you gotta use the function. 💅

and layer can take on these values, which tell it which layer mode to use:

• GLUT_NORMAL
• GLUT_LAYER

those are the two moods. pick one. 🌈

---

💀 CAVEATS 💀

Unimplemented. yeah. it's giving "coming soon" energy but with zero promise of soon. do not build your whole app around this one, bestie, i'm begging 😭

and then there's the part where nobody actually knows what happens if you're sitting in GLUT_OVERLAY mode and then you switch to another window (or even the same window) via glutSetWindow(). like… what if the target window has a layer? 🫠 what if it doesn't?? literally nobody has the answers here. this is the undefined-behaviour part of the group chat and we are all just sitting in it. 🔥

okay that's the whole page!! 💜 this icon of a doc is dated UNDATED and its source is UNTITLED(), which honestly is such a mood — no date, no title, just vibes. stay slay, protect your layers, and remember: unimplemented means do not. mwah 🎀✨🦋
