XpQueryExtension(3Xp)

💖 NAME 💖

Okay bestie, this is the XpQueryExtension(3Xp) page from the XPRINT FUNCTIONS crew ✨ — and it's literally the “does this server even support the X Print Service Extension?” check. XpQueryExtension asks an X Server if it supports the X Print Service Extension, and if it does, what the offsets are for associated events and errors. No cap.

✨ SYNOPSIS ✨

      cc [ flag... ] file... -lXp [ library... ]
      #include <X11/extensions/Print.h>

Bool XpQueryExtension ( display, event_base_return error_base_return )
      Display *display;
      int *event_base_return;
      int *error_base_return;

🎀 ARGUMENTS 🎀

• display — a pointer to the Display structure, returned from XOpenDisplay. That's your main-character server connection, periodt 💅
• event_base_return — the base value for X Print Service Extension events.
• error_base_return — the base value for X Print Service Extension errors.

🦋 DESCRIPTION 🦋

XpQueryExtension determines if the X Print Service Extension is present. It returns True if the extension is supported, otherwise False. If the extension is present, the base values for events and errors are returned, and they can be used to decode incoming event and error values. Obsessed with a clean little vibe check. 💅

The X Print Service Extension is initialized on the first call to any X Print Service function; there is no need to explicitly initialize the X Print Service Extension. So don't stress about setting it up first — it handles itself. 🫶

And that's the whole page, bestie 💖 — brought to you by X Version 11 and libXp 1.0.4, with footer energy from XpQueryExtension(3Xp) and no date listed on the page. Slay, secure, and send it. 🎀
