πŸ’… xcb_install_colormap β€” a whole vibe from the XCB Requests manual

okay bestie, sit down, hydrate, because we're getting into xcb_install_colormap(3) from the XCB Requests manual and honestly? she's a short one. no cap, this page is mostly vibes and one function signature. let's go ✨


✨ NAME ✨

xcb_install_colormap β€”

and that's it. that's the whole name entry. the original page literally just trails off after the dash. the description is giving mysterious main character energy. we move πŸ’…


🌸 SYNOPSIS 🌸

first thing, before anything else, you gotta pull in the header:

#include <xcb/xproto.h>

πŸŽ€ Request function πŸŽ€

here's the girl herself:

xcb_void_cookie_t xcb_install_colormap(xcb_connection_t *conn,
       xcb_colormap_t cmap);

she takes two things and returns a cookie. not the edible kind (sadly πŸͺ), the async kind.


πŸ¦‹ REQUEST ARGUMENTS πŸ¦‹

  • conn β€” your XCB connection to X11. that's the lil thread between you and the X server. your connection, your bestie, your situationship with the display πŸ’œ
  • cmap β€” so... the manpage says literally TODO: NOT YET DOCUMENTED. and like, not me reading the source docs and finding a TODO 😭 the authors fr fr said "we'll get to it." so bestie, i am NOT gonna sit here and make up what cmap does, because that would be lying to you and lying is not the move. it's a xcb_colormap_t. that's what we know. that's what we're standing on. periodt.

πŸ’€ DESCRIPTION πŸ’€

ngl bestie, there is no description. the section is there. it is empty. it's giving "the group chat is typing… and then stops." 🫢

so yeah β€” no prose, no explanation, no lore. i can't invent it for you. if you want the actual story of what installing a colormap does, that's a you-and-the-X-protocol-spec situation. i'm just here to tell you the section exists and it is empty.


⭐ RETURN VALUE ⭐

she returns an xcb_void_cookie_t. and because this is the async girlie side of XCB, errors (if any) have to be handled in the event loop. so don't be out here assuming everything's fine just because you got a cookie back β€” you gotta actually go check, iykyk.

but wait, what if you're not an event-loop kinda person and you want to just handle errors directly? okay so if you'd rather do that with xcb_request_check instead, then use xcb_install_colormap_checked. that's the whole trade: async version + event loop, or checked version + direct checking.

for the full tea on how request checking works, see xcb-requests(3). πŸ“–


πŸ™ˆ ERRORS πŸ™ˆ

This request does never generate any errors.

slay. no errors, no drama, no nothing. she simply does not miss πŸ’…βœ¨


🌈 SEE ALSO 🌈

and this section? also empty bestie. no cross-references, no friends, no link-outs. she's a lone wolf. a solo act. the main character of her own little empty section. 😭

πŸ‘‘ AUTHOR πŸ‘‘

this page was Generated from xproto.xml. so like, it wasn't even handwritten by a human β€” it got machine-spat-out from an XML file, which honestly explains the TODO and the empty sections fr fr πŸ’€

if you spot something wrong or you wanna slide in with corrections and improvements, you contact: xcb@lists.freedesktop.org

that's the email. be normal about it. πŸ™ˆ


okay and that's the whole page!! thank you for coming to my ted talk, she was short but she was iconic, no cap, ate and left no crumbs πŸŽ€βœ¨

sending you off with the official receipts: this page is from X Version 11, specifically libxcb 1.17.0, and yes, she's still xcb_install_colormap(3) all the way down. bye bestie, go install a colormap or whatever πŸ’–πŸ¦‹πŸŒΈ
