GLUCHECKEXTENSION(3G)

💅 GLUCHECKEXTENSION (3G) ✨

okay bestie, welcome to the GLUCHECKEXTENSION(3G) page — yes the title is doing all caps but we can still make it cute 🎀

---

🌸 NAME 🌸

gluCheckExtension — figures out if an extension name is actually supported 🦋

---

✨ C SPECIFICATION ✨

GLboolean gluCheckExtension( const GLubyte *extName,
                             const GLubyte *extString )

like. that's it. that's the whole vibe. 💖

---

🎀 PARAMETERS 🎀

• extName — the extension name you're asking about, bestie. just one name.
• extString — a space-separated list of the extension names that are supported. so like, the whole roster. 👑

---

💖 DESCRIPTION 💖

gluCheckExtension returns GL_TRUE if extName is supported, and otherwise GL_FALSE gets returned. simple as that, no cap. ✅

this is the move when you wanna check for the presence of OpenGL, GLU, or GLX extension names — you pass in the extension strings that come back from glGetString, gluGetString, glXGetClientString, glXQueryExtensionsString, or glXQueryServerString, respectively, as your extString. yep, respectively. we're being precise here. 🫶

💀 NOTES 💀

okay so the little gotchas, listen up:

• cases where one extension name is a substring of another one are correctly handled. the way that it does NOT get confused?? iconic. 🔥
• there may or may not be leading or trailing blanks in extString. either way. we don't judge. 🙈
• extension names should not contain embedded spaces. like, please. just don't. 😭
• all strings are null-terminated. every single one. periodt. 💅

🌈 SEE ALSO 🌈

• glGetString(3G)
• gluGetString(3G)
• glXGetClientString(3G)
• glXQueryExtensionsString(3G)
• glXQueryServerString(3G)

go read those too, they're giving main character energy 👑

and that's the whole page, bestie!! the footer is just GLUCHECKEXTENSION(3G) again — that's the manual name and the source/version line, and ngl there's no date up in here, so that's all she wrote. mwah. 💋🦋
