---

✨ NAME ✨

xcb_glx_query_extensions_string — and that's it, that's the whole description, the original page literally leaves it blank so I'm not gonna invent lore for it 🫶

---

🌸 SYNOPSIS 🌸

First thing, you gotta pull in the header:

#include <xcb/glx.h>

🎀 Request function

xcb_glx_query_extensions_string_cookie_t
xcb_glx_query_extensions_string(xcb_connection_t *conn,
              uint32_t screen);

🦋 Reply datastructure

typedef struct xcb_glx_query_extensions_string_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint8_t  pad1[4];
    uint32_t n;
    uint8_t  pad2[16];
} xcb_glx_query_extensions_string_reply_t;

🧚 Reply function

xcb_glx_query_extensions_string_reply_t
       *xcb_glx_query_extensions_string_reply(xcb_connection_t *conn,
              xcb_glx_query_extensions_string_cookie_t cookie,
              xcb_generic_error_t **e);

🌈 REQUEST ARGUMENTS 🌈

• conn — your XCB connection to X11, the whole link to the server, the main character fr.
• screen — TODO: NOT YET DOCUMENTED. yeah bestie, the docs really said "figure it out" 😭 it's a uint32_t, that's what we know.

---

⭐ REPLY FIELDS ⭐

• response_type — the type of this reply, and in this case it's XCB_GLX_QUERY_EXTENSIONS_STRING. plot twist: this field also lives in xcb_generic_reply_t, so you can use it to tell replies apart from each other. iconic behavior tbh.
• sequence — the sequence number of the last request processed by the X11 server. it's giving receipts 📋
• length — the length of the reply, in words (and a word is 4 bytes, don't forget, that's the whole trick).
• n — TODO: NOT YET DOCUMENTED. another mystery, we stay humble 🙈

💜 DESCRIPTION 💜

...so the original page has literally nothing here. no cap. empty. blank. the vibe is immaculate but the content is not present 😭 we move on.

---

🔥 RETURN VALUE 🔥

Returns an xcb_glx_query_extensions_string_cookie_t. Errors have to be handled when calling the reply function xcb_glx_query_extensions_string_reply.

If you want to handle errors in the event loop instead, use xcb_glx_query_extensions_string_unchecked. See xcb-requests(3) for details. yes bestie, that's a whole other manpage, go read it 🫶
