XCB_GLX_GET_MINMAX_PARAMETERIV_UNCHECKED(3)

xcb_glx_get_minmax_parameteriv 💅✨

okay bestie, welcome to the XCB Requests chapter of your life 🎀 this one's a libxcb request page, and no cap, it is extremely niche. it's giving "GLX minmax parameter, but make it iv". let's get into it 🦋

---

✨ NAME ✨

xcb_glx_get_minmax_parameteriv — and that's genuinely it, the original NAME section is just a lil dash with nothing after it 🙈 the name is the whole personality here.

---

🌸 SYNOPSIS 🌸

First things first, you gotta bring in the header, periodt:

#include <xcb/glx.h>

💖 Request function

xcb_glx_get_minmax_parameteriv_cookie_t
       xcb_glx_get_minmax_parameteriv(xcb_connection_t *conn,
       xcb_glx_context_tag_t context_tag, uint32_t target,
       uint32_t pname);

💖 Reply datastructure

here's the reply struct, look at her 👑

typedef struct xcb_glx_get_minmax_parameteriv_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint8_t  pad1[4];
    uint32_t n;
    int32_t  datum;
    uint8_t  pad2[12];
} xcb_glx_get_minmax_parameteriv_reply_t;

💖 Reply function

xcb_glx_get_minmax_parameteriv_reply_t
       *xcb_glx_get_minmax_parameteriv_reply(xcb_connection_t *conn,
       xcb_glx_get_minmax_parameteriv_cookie_t cookie,
       xcb_generic_error_t **e);

💖 Reply accessors

these are the lil helpers that reach into the reply for you, so you don't have to do the pointer math yourself (we love her for that) 🫶

int32_t *xcb_glx_get_minmax_parameteriv_data(const
       xcb_glx_get_minmax_parameteriv_request_t *reply);

int xcb_glx_get_minmax_parameteriv_data_length(const
       xcb_glx_get_minmax_parameteriv_reply_t *reply);

xcb_generic_iterator_t xcb_glx_get_minmax_parameteriv_data_end(const
       xcb_glx_get_minmax_parameteriv_reply_t *reply);

🎀 REQUEST ARGUMENTS 🎀

• conn — the XCB connection to X11. your main character, fr.
• context_tag — TODO: NOT YET DOCUMENTED. (not me getting nothing from the docs 😭)
• target — TODO: NOT YET DOCUMENTED. (same energy 💀)
• pname — TODO: NOT YET DOCUMENTED. (they really said "figure it out bestie" 🙈)

---

🦋 REPLY FIELDS 🦋

• response_type — the type of this reply, and in this specific case it's XCB_GLX_GET_MINMAX_PARAMETERIV. this field is also chillin' inside the xcb_generic_reply_t, and you can use it to tell replies apart from each other. lowkey iconic for that.
• sequence — the sequence number of the last request that the X11 server processed. it's giving "where were we" energy.
• length — how long the reply is, in words. and yes, a word here is 4 bytes. remember that, iykyk.
• n — TODO: NOT YET DOCUMENTED. (bestie the docs are empty 💀)
• datum — TODO: NOT YET DOCUMENTED. (yeah. also empty. we move.)

---

💜 DESCRIPTION 💜

...yeah there's literally nothing here. the DESCRIPTION section is empty. it's giving silence, it's giving mystery, it's giving "the source code is the documentation" 🧚 no cap, that's just how this page is.

---

🌈 RETURN VALUE 🌈

okay so you get back an xcb_glx_get_minmax_parameteriv_cookie_t. cute. but here's the thing — errors have to be handled when you call the reply function, xcb_glx_get_minmax_parameteriv_reply.

if you'd rather handle errors in the event loop instead (very valid, very main character of you), use xcb_glx_get_minmax_parameteriv_unchecked. and go read xcb-requests(3) for the details, she explains it all 💅

---

🔥 ERRORS 🔥

This request does never generate any errors. 🎉

no errors, no drama, we love a clean run. periodt.

---

⭐ SEE ALSO ⭐

...the original page has nothing listed under SEE ALSO. iconic of her honestly. (though xcb-requests(3) does get a shoutout up in RETURN VALUE, so go say hi 👋)

👑 AUTHOR 👑

Generated from glx.xml. if you've got corrections or improvements, hit up xcb@lists.freedesktop.org — they're literally asking for it, so don't be shy bestie 💌

and that's the whole page, babe 🌸 this was X Version 11, from libxcb 1.17.0 — so if you were out here wondering where this came from, now you know. go forth and get those minmax parameteriv values, you absolute legend 🦋✨💖
