🌸 PARAMETERS 🌸

• dpy — the connection to the X server, your lil phone line to the server basically 📞
• ctx — a GLX rendering context, the actual thing we're talking about 💅

💖 DESCRIPTION 💖

Okay so here's the tea ☕: glXFreeContextEXT frees the client-side part of a GLXContext that was created with glXImportContext. That's it, that's the whole job, and she does it well 👑

But bestie, listen, this is the important part: glXFreeContextEXT does not free the server-side context information, and it does not free the XID associated with the server-side context. So like… half the context is still out there living its life 🙈 the client-side memory is gone, the server-side stuff is not.

glXFreeContextEXT is part of the EXT_import_context extension, not part of the core GLX command set. She's a guest star, not a series regular ✨

And the vibe check on whether the extension is even there: if GLX_EXT_import_context is included in the string returned by glXQueryExtensionsString, when called with argument GLX_EXTENSIONS, extension EXT_vertex_array is supported. 👀 (yes, that's exactly what it says, no I will not elaborate, the manpage said it and I'm just the messenger 🫶)

---

😭 ERRORS 😭

GLXBadContext is generated if ctx does not refer to a valid context. So if you hand her a fake context, she WILL clock it and throw hands 💀

And that's the whole page, babe 🫶 this was the GLXFREECONTEXTEXT() man page from the 3G manual — the source line just says GLXFREECONTEXTEXT() on both ends, iconic symmetrical queen behavior 👑 no cap. Go free your contexts responsibly, mwah 💜
