GLUTTIMERFUNC(3)

✨ glutTimerFunc — bestie edition ✨

okay so this is the OpenGLUT manual page for glutTimerFunc, and it lives in the idletimer section of the OpenGLUT library. it's giving "set a little alarm clock for your window" energy and honestly? iconic. 💖

🌸 LIBRARY 🌸

OpenGLUT — idletimer

---

🎀 SYNOPSIS 🎀

#include <openglut.h>

void
glutTimerFunc(unsigned int msec, void( *callback )( int data ),
    int data);

like. look at her. three args. no notes. 💅

---

🦋 PARAMETERS 🦋

• msec — how many milliseconds until we fire this thing off. the countdown, the anticipation, the drama. ⏳
• callback — your very own client function, the one that gets to run when the timer event hits. your moment, your main character arc. 👑
• data — arbitrary data, no questions asked, and it gets passed straight through to callback. you hand it over, it shows up on the other side. fr fr. 🫶

---

🌈 DESCRIPTION 🌈

after at least msec milliseconds, OpenGLUT will call your callback, and it'll pass in that user-supplied data parameter you gave it. 💫

heads up bestie: OpenGLUT calls your function only once. one and done. periodt.

and lowkey the most important part — this callback is not bound to any window. it's free-floating, windowless, just out here vibing on its own. 🧚

---

💀 CAVEATS 💀

okay so this is the part where we get real, because timers are a little different from the other callbacks and you need to know that going in:

• Unlike most other callbacks, timers only occur once. not a loop. not a vibe. one shot. 😭
• Unlike most other callbacks, you cannot deregister a timer callback. no take-backs, no undo, no "nvm". 🙈
• Unlike most other callbacks, you can register an arbitrary number of timers. go off, register forty of them, live your truth. 🔥

and that's the whole page, bestie!! 🍓 this one's UNDATED and the footer just says UNTITLED(), which is honestly so mysterious of it. no version, no date, just vibes. go forth and schedule your little callbacks. mwah. 💜✨
