GLUTIDLEFUNC(3)

💖 glutIdleFunc(3) 💖

okay bestie, pull up a chair, we're talking about glutIdleFunc from the OpenGLUT manual, section 3 (idletimer, if you're keeping track) ✨

---

🦋 NAME 🦋

glutIdleFunc — sets the global idle callback. that's it, that's the whole vibe 💅

---

📚 LIBRARY 📚

OpenGLUT — idletimer 🎀

---

✨ SYNOPSIS ✨

#include <openglut.h>

void
glutIdleFunc(void( *callback )( void ));

like. look at her. so clean. so simple. iconic 👑

---

🌸 PARAMETERS 🌸

• callback — the client function for the idle event. this is the lil' bestie you hand over and say "hey, run this when you're bored" 🫶

---

💜 DESCRIPTION 💜

so here's the tea: when OpenGLUT's glutMainLoop() is doing nothing else — literally nothing, just sitting there with no plans — it checks to see if an `idle` callback has been set. and if one has been set?? bestie. it invokes that callback. periodt. 🔥

lowkey important: this callback is not bound to any window. no window. none. it's a free agent, a main character with no address 😭

---

💀 CAVEATS 💀

okay so listen, this is the part where you gotta pay attention:

there is at most one idle callback for your entire application. one. uno. singular. for the whole app. so don't be out here thinking you can collect idle callbacks like Pokémon cards, because you cannot 🙈

this lil' baddie comes to you courtesy of the OpenGLUT manual, dated UNDATED, and it's rockin' the page footer UNTITLED() — mysterious, unbothered, timeless. honestly? she's giving enigma ✨🎀💅
