GLUGETSTRING(3G)

✨ GLUGETSTRING ✨

okay bestie, welcome to the 3G manual, this one's called gluGetString and it's literally just "hey GLU, what version are you and what extensions you got" 💅

---

🌸 NAME 🌸

gluGetString — returns a string describing the GLU version or GLU extensions 🦋

---

🎀 C SPECIFICATION 🎀

const GLubyte * gluGetString( GLenum name )

---

💖 PARAMETERS 💖

• name — you hand it a symbolic constant, and it's gotta be one of GLU_VERSION or GLU_EXTENSIONS. That's the whole vibe check. 👑

---

🌈 DESCRIPTION 🌈

So gluGetString gives you back a pointer to a static string that describes the GLU version, or the GLU extensions that are supported. Either/or, depends on what you asked for. ✨

The version number comes in one of these forms, no cap:

major_number.minor_number
major_number.minor_number.release_number.

And the version string itself looks like this:

version number<space>vendor-specific information

Vendor-specific info is optional. And its ... and contents depend on the implementation (yes bestie the original wording is a little cursed there, but that's genuinely what it says, I'm not gonna lie to you 😭).

The standard GLU contains a basic set of features and capabilities. If a company, or a lil group of companies, wants to support other features, those can get included as extensions to the GLU. So if name is GLU_EXTENSIONS, then gluGetString returns a space-separated list of the names of the supported GLU extensions. (Extension names never contain spaces, so that list actually parses. iconic.) 🫶

All strings are null-terminated. periodt. 💀

---

👑 NOTES 👑

gluGetString only returns info about GLU extensions. If you want a list of GL extensions, you gotta call glGetString instead. Different function, different vibe. 🦋

gluGetString is an initialization routine. Calling it after a glNewList results in undefined behavior. So like, do not do that. I'm serious. 🙈

---

💀 ERRORS 💀

NULL is returned if name is not GLU_VERSION or GLU_EXTENSIONS. Wrong question, no answer. ✨
