GLXGETCONTEXTIDEXT(3gl)

💅 GLXGETCONTEXTIDEXT 💅

okay bestie, welcome to the glXGetContextIDEXT page from the 3G manual ✨ this one's short and sweet and lowkey iconic, let's get into it 🫶

---

✨ NAME ✨

glXGetContextIDEXT — get the XID for a context 💖

---

🌸 C SPECIFICATION 🌸

GLXContextID glXGetContextIDEXT( const GLXContext ctx )

delim $$

(yeah the delim $$ line is just sitting there being mysterious, we don't ask questions, we respect it 💅)

---

🎀 PARAMETERS 🎀

• ctx — specifies a GLX rendering context. that's it. that's the whole vibe check. it's the context you're asking about, no cap 🦋

---

💖 DESCRIPTION 💖

so glXGetContextIDEXT returns the XID associated with a GLXContext. that's literally the whole job, and it does it flawlessly, main character energy fr fr ✨

here's the part that's actually kind of a slay: no round trip is forced to the server. the way that it just hands you the value without bothering the server?? obsessed. unlike most X calls that return a value, glXGetContextIDEXT does not flush any pending events. so it's fast, it's chill, it's not out here disturbing the event queue 💅

now the lore 🧚: glXGetContextIDEXT is part of the EXT_import_context extension, not part of the core GLX command set. so if you're wondering whether it's supported — if GLX_EXT_import_context is included in the string returned by glXQueryExtensionsString, when called with argument GLX_EXTENSIONS, then extension EXT_import_context is supported. periodt. 👑

---

😭 ERRORS 😭

• GLXBadContext is generated if ctx does not refer to a valid context. so like… give it a real context bestie, don't set it up to fail 🙈

---

🔥 SEE ALSO 🔥

• glXCreateContext
• glXQueryVersion
• glXQueryExtensionsString

go read those too, they're the friend group 🌈

and that's the whole page!! mwah 💖 this lil beauty lives in the GLXGETCONTEXTIDEXT page of the 3G manual, and it says its name right there at the bottom like a signature. take care of your contexts, drink water, and remember: no round trip, no pending-event flush, no problem 🎀✨💜
