GLUTGETPROCADDRESS(3)

🎀 GLUTGETPROCADDRESS 💅

okay bestie, so this is a page from the OpenGLUT manual — library name's literally openglut, no cap — and it's all about that glutGetProcAddress life. it's the "hey is this thing even here??" function. let's get into it ✨

✨ SYNOPSIS ✨

#include <openglut.h>

void
glutGetProcAddress(const char *procName);

🌸 PARAMETERS 🌸

• procName — the name of the procedure. that's it, that's the whole vibe. it's a string, bestie. the name of the function you're hunting for 👑

💖 DESCRIPTION 💖

okay so here's the tea. you hand it a function name, and it goes digging through the internal tables looking for that function (or "procedure" — hence the Proc in the name, iykyk). if it finds it? boom, you get a pointer to the function back. if it doesn't find it? you get NULL. that's the whole deal. 💀

and it doesn't stop at the internal OpenGLUT table either — it's giving main character energy and going the extra mile. if the OpenGLUT tables don't have the function you asked for, it will also go consult:

• glX — on X systems 🖥️
• wgl — on WIN32 and WINCE 🪟

so like, it should return any OpenGL, glX, or wgl function, as long as those functions are actually available. she's thorough, she's resourceful, she ate. 🫶

🙈 CAVEATS 🙈

not me being the bearer of bad news but… the code makes no effort towards efficiency. none. zero. it's not even trying, bestie. 😭

so the advice is: if you need a certain function repeatedly, please please please cache the pointer you got from this function. don't be out here calling it in a loop, that's not the move. save the pointer, live your life. 💅

go read those too, they're the cousins fr fr 🦋

and that's the whole page!! this one came from OpenGLUT, it's dated UNDATED, and the footer situation is literally UNTITLED() — mysterious, iconic, we love a blank signature moment ✨💖 slay, go cache your pointers, mwah 🎀
