XtInitialize(3)

💖 XtInitialize(3) — XT COMPATIBILITY FUNCTIONS 💖

okay bestie, buckle up, because we're in the compatibility functions section of the X Toolkit Intrinsics, manual section 3, and this one is a certified throwback 👑✨

---

✨ NAME ✨

XtInitialize — initialize 🎀

(yes that's the whole name section, she's short and mysterious, we love that for her)

---

🌸 SYNTAX 🌸

#include <X11/Intrinsic.h>

Widget XtInitialize(const char *shell_name, const char
       *application_class, XrmOptionDescRec* options, Cardinal
       num_options, int* argc, char** argv);

---

🦋 ARGUMENTS 🦋

• shell_name — the name you're giving to the shell widget that gets created. you pick it, you name it, you own it 💅
• application_class — the class name of this app. and like, it's usually the generic name that covers every single instance of this application, so think of it as the family name, not the government name.
• options — tells the toolkit how to parse the command line for any app-specific resources. this bad boy gets passed straight through as a parameter to XrmParseCommand. want the deets? go read Xlib - C Language X Interface, she has the lore 📖
• num_options — how many entries are in that options list. count them. fr fr.
• argc — a pointer to the number of command line parameters. a pointer, bestie, not the value itself. she's indirect like that 🫶
• argv — the actual command line parameters. the real ones.

---

💜 DESCRIPTION 💜

so here's the tea on what XtInitialize actually does when you call her:

1. she calls XtToolkitInitialize first, like a little warm-up stretch 🧚
2. then she calls XtOpenDisplay with display_string as NULL and application_name as NULL
3. and finally she calls XtAppCreateShell with application_name NULL, widget_class set to applicationShellWidgetClass, plus the args and num_args you specified
4. and then she hands you back the created shell. slay. ✨

⚠️ the semantics of calling XtInitialize more than once are undefined. not "probably fine," not "usually works" — undefined. do not do it. not even once more. i'm so serious 😭

also, this routine has been replaced by XtAppInitialize. she's the upgraded version. XtInitialize is giving legacy icon energy — iconic, but retired 👑

and that's the whole page, no cap 🫶 this was X Version 11, libXt 1.3.1, straight out of the XtInitialize(3) manual page — go forth and initialize responsibly, bestie 💖🌸🦋
