XtAppGetErrorDatabase(3)

💖 XtAppGetErrorDatabase — the manual page, bestie edition 💖

okay so you're in XT FUNCTIONS land, this is the XtAppGetErrorDatabase(3) page, and it's literally just about ✨obtaining the error database✨. two functions, one mission, let's go 🫶

---

✨ NAME ✨

XtAppGetErrorDatabase, XtAppGetErrorDatabaseText — obtain error database 🎀

---

✨ SYNTAX ✨

first, you gotta bring in the header, no cap:

#include <X11/Intrinsic.h>

then, the two icons themselves:

XrmDatabase *XtAppGetErrorDatabase(XtAppContext app_context);

void XtAppGetErrorDatabaseText(XtAppContext app_context, const char
       *name, const char *type, const char *class, const char
       *defaultMsg, char *buffer_return, int nbytes, XrmDatabase
       database);

---

✨ ARGUMENTS ✨

here's the whole cast, every single one, no skips 💅

• app_context — specifies the application context. yeah she's the main character, everything runs through her.
• buffer_return — specifies the buffer into which the error message is to be returned. that's where the message comes home to 🏠
• class — specifies the resource class of the error message.
• database — specifies the name of the alternative database that is to be used, or NULL if the application's database is to be used. so like, bring your own database or just use the app's, your call 🌸
• defaultMsg — specifies the default message to use. the fallback bestie.
• name, type — specifies the name and type that are concatenated to form the resource name of the error message. they team up. it's giving duo energy 👑
• nbytes — specifies the size of the buffer in bytes.

---

✨ DESCRIPTION ✨

so XtAppGetErrorDatabase returns the address of the error database. that's it, that's the whole vibe. 📬

⚠️ but here's the tea: the Intrinsics do a lazy binding of the error database. they do not merge in the database file until the first call to XtAppGetErrorDatbaseText. yes, lazy. she'll get to it when she gets to it 💀

and XtAppGetErrorDatabaseText returns the appropriate message from the error database, or returns the specified default message if one is not found in the error database. found it? slay. not found? you get defaultMsg, and honestly that's still valid 🦋
