💖 DMXQueryVersion(3) 💖

okay bestie, so this is a page from the Library Functions Manual, and it's all about DMXQueryVersion — the little function that tells you what version of the DMX protocol extension you're actually dealing with. no cap. let's get into it 🦋

✨ NAME ✨

DMXQueryVersion — figure out the DMX extension version, that's it, that's the whole job 💅

🌸 SYNOPSIS 🌸

#include <X11/extensions/dmxext.h>

Bool DMXQueryVersion(Display *dpy,
                     int *major_version,
                     int *minor_version,
                     int *patch_version);

like, look at her. four args. she's serving. 🎀

💜 DESCRIPTION 💜

DMXQueryVersion() hands you back version info about the DMX protocol extension. that's the vibe. 🔥

now here's how the three numbers work, and this part is lowkey important:

  • any incompatible changes to the protocol? those get flagged by a change in major_version. big deal energy.
  • small, upward-compatible changes? those show up as a change in minor_version. cute little glow-up.
  • and patch_version? in general that one's just for informational purposes — it encodes the date of the last protocol revision (like, for example, 20040604). it's giving timestamp. 📅

🫶 RETURN VALUE 🫶

if the DMX protocol extension is available, then major_version, minor_version, and patch_version all get set, and you get True back. slay. ✨

otherwise? you get False. that's it. no version info for you. 😭

👑 NOTES 👑

at the time of this writing, the DMX protocol is at version 2.2. periodt.

version 2.2 was the final development version, and the code supporting it was submitted to upstream X server repositories in the summer of 2004. history icon honestly.

version 1.5 was the last of the 1.x series — that one was used for development before screen and input addition and removal were supported. then version 2.0 and 2.1 were development versions that partially supported screen and input addition and removal. half-baked era, we don't talk about it 💀

so here's the recommendation, bestie: since we do not expect development versions to be widely used, we recommend that any software using the DMX protocol extension support only versions 2.2 and above. that said — they should still detect earlier versions and either reduce functionality or fail gracefully. no crashing out in the group chat, okay? 🙈

🌈 SEE ALSO 🌈

and that's the whole page, babe 💖 this came to you from X Version 11, libdmx 1.1.5, and yes, DMXQueryVersion(3) is the moment. go check your versions, stay compatible, and remember: fail gracefully always. mwah 🎀✨💅
