XtGetDisplays(3)

💅 XtGetDisplays — the <X11/Intrinsic.h> era, bestie edition

okay so this is a page from the XT FUNCTIONS manual, and it's all about XtGetDisplays — one little function that hands you back every display your app context is holding onto. short page, but it's lowkey important. let's go ✨

---

🌸 NAME 🌸

XtGetDisplays — retrieve a list of displays associated with an application context. that's the whole vibe: you have an app context, it has displays, you want the receipts. periodt.

---

✨ SYNTAX ✨

#include <X11/Intrinsic.h>

void XtGetDisplays(XtAppContext app_context, Display ***dpy_return,
       Cardinal* num_dpy_return);

look at that triple pointer. Display ***?? she's giving main character energy fr fr 😭

🎀 ARGUMENTS 🎀

• app_context — Specifies the application context. you're telling her which app context to go snooping in 💖
• dpy_return — Returns a list of open X display connections in the specified application context. yes, it's a triple pointer, yes it's iconic, no we are not going to talk about it 💅
• num_dpy_return — Returns the count of open X display connections in dpy_return. so you know how many little display besties you just got handed 🦋

---

💀 DESCRIPTION 💀

To free the list of displays, use XtFree.

that's it. that's the whole description. not me getting emotional over a three-word manpage 🥹

but seriously bestie, don't forget the XtFree. that list is yours now — the function gave it to you, and nobody else is gonna clean it up. free the list, protect your memory, slay responsibly 🫶

and that's the whole page!! this one's from X Version 11, shipped with libXt 1.3.1, and the footer date stamp on the original is the same as the version block — so go forth, grab your displays, and XtFree them when you're done. mwah 💋👑

XtGetDisplays(3) — she's short, she's sweet, she leaks memory if you ignore her. no cap. 🎀
