DTAPPINITIALIZE(3)

💖 NAME 💖

okay so bestie, meet DtInitialize and DtAppInitialize — the two functions that initialize the Desktop Services library. that's it, that's the whole job, and they take it very seriously ✨

(this one's a library call page, if you were wondering — like, the manual section energy is "library call", not a command you type in your shell 🫶)

🌸 SYNOPSIS 🌸

here's the whole thing, bestie — copied exactly, no edits, no vibes-based corrections, i promise:

#include &<Dt/Dt.h>
Boolean DtInitialize(
Display *display,
Widget widget,
char *name,
char *tool_class,
Boolean DtAppInitialize(
XtAppContext app_context,
Display *display,
Widget widget,
char *name,
char *tool_class);

like yes the #include line has a little & gremlin in it and yes DtInitialize's signature is missing its closing paren up there — that's literally how it's printed, so i'm not touching it. we respect the source 💅

🦋 DESCRIPTION 🦋

so these functions do the one-time initialization for the Desktop Services library. one time. that's the whole bit. 🎀

and this part is not a suggestion, it's a rule: applications must call either DtInitialize or DtAppInitialize before calling any other Desktop Services library routines. like, before. any of them. no skipping the line, no "i'll do it later", no cap 😭

the difference between the two? literally just whether app_context gets specified or not. that's the entire plot twist:

  • DtInitialize uses the default Intrinsic XtAppContext — it just grabs the default one, no questions asked 🧚
  • DtAppInitialize — you hand it the context yourself

and here's what all the arguments mean, in order:

  • app_context — the application context (this one's DtAppInitialize-only, obviously)
  • display — the X display connection
  • widget — the application's top-level Widget
  • name — the application name
  • tool_class — the application class

⭐ RETURN VALUES ⭐

upon successful completion, DtAppInitialize and DtInitialize return True — but only if the library has been correctly initialized. otherwise? they return False. simple as that. no weird in-between, no "kinda true", no undefined vibes. 🔥

ngl, this is the easiest return value check you'll ever write — just look for True and you're golden 👑

🌈 SEE ALSO 🌈

go read these next, bestie, they're the whole friend group:

and that's the page!! 💜 cute little sign-off time: this footer is literally just DtInitialize(library call) again — no date, no version number, nothing extra, the manpage said "that's it" and walked away 🎀 so yeah, that's the source as printed, bestie. slay, go initialize something 🦋✨
