GLUTLAYERGET(3)

💖 glutLayerGet(3) — the layer-vibe check 💖

okay bestie so this one lives in the OpenGLUT manual, section 3 (the library-function girlies), and it's filed under overlays. her whole job? let you peek at some overlay state/option variables. iconic behaviour, honestly.

✨ LIBRARY ✨

OpenGLUT - overlays

---

🌸 SYNOPSIS 🌸

#include <openglut.h>

int
glutLayerGet(GLenum eWhat);

---

🎀 PARAMETERS 🎀

• eWhat — the enumerated parameter ID, aka the little ticket that says which thing you're asking about. 💅

---

🦋 DESCRIPTION 🦋

she returns some genuinely useful info about layers. or… she would be useful if layers were actually implemented 😭💀 that's the tea, no cap.

eWhat can be handed any one of these values:

• GLUT_HAS_OVERLAY
• GLUT_LAYER_IN_USE
• GLUT_NORMAL_DAMAGED — comes back 0 unless the window system has told us the normal layer is damaged. and bestie, listen: glutPostRedisplay() does not affect this one. 🙈
• GLUT_OVERLAY_DAMAGED — -1 if no layer in use.
• GLUT_OVERLAY_POSSIBLE
• GLUT_TRANSPARENT_INDEX — -1 if no layer in use.

heads up: all of this info relates to the current window and any overlay it may have. so like, know which window you're talking about, fr fr. 👑
