GLUTGETWINDOWDATA(3)

🫶 LIBRARY 🫶

OpenGLUT - window

It's giving window-library energy, no cap. ✨

🎀 SYNOPSIS 🎀

#include <openglut.h>

void*
glutGetWindowData(void);

💅 DESCRIPTION 💅

Okay so this function will return whatever void* value is associated with the current window via glutSetWindowData(). That's the whole vibe. If you did not associate a pointer with your window, this is NULL. 🙈

This can be useful in a situation where you have a single callback function performing services for many windows. You could keep track of the window id s in a global list and search for the current window in that list. But this is quicker than searching a data structure, and it allows you to avoid the use of globals for this. Periodt. 👑
