REQUEST ARGUMENTS 🍓

• conn — the XCB connection to X11. your lil hotline to the server, fr fr.
• old_context_tag — TODO: NOT YET DOCUMENTED.
• drawable — TODO: NOT YET DOCUMENTED.
• read_drawable — TODO: NOT YET DOCUMENTED.
• context — TODO: NOT YET DOCUMENTED.

not the docs ghosting us on four whole arguments 😭 that's literally what the original says though, so we're not making stuff up. periodt.

REPLY FIELDS ⭐

• response_type — the type of this reply, which in this case is XCB_GLX_MAKE_CONTEXT_CURRENT. this field also lives in the xcb_generic_reply_t, so you can use it to tell your replies apart from each other. it's basically the reply's little name tag 🏷️
• sequence — the sequence number of the last request processed by the X11 server.
• length — the length of the reply, in words. and a word is 4 bytes, iykyk.
• context_tag — TODO: NOT YET DOCUMENTED.

DESCRIPTION 💀

...yeah. the original description section is empty. we are simply not going to invent lore, bestie. moving on 🧚

---

RETURN VALUE 🌈

Returns an xcb_glx_make_context_current_cookie_t. Errors have to be handled when calling the reply function xcb_glx_make_context_current_reply.

If you want to handle errors in the event loop instead, use xcb_glx_make_context_current_unchecked. See xcb-requests(3) for details.

cookie first, then you go back for the reply. it's giving "order your drink, then pick it up at the counter" ☕

---

ERRORS 🙈

This request does never generate any errors. zero drama, zero chaos, she's well-behaved 💅

---

SEE ALSO 💜

the original lists nothing here. nothing!! we're honoring the void 🕳️✨
