XpQueryExtension(3Xp)	       XPRINT FUNCTIONS		 XpQueryExtension(3Xp)

NAME
       XpQueryExtension	 - Queries an X	Server to determine if it supports the
       X Print Service Extension, and if it does, what the offsets are for as-
       sociated	events and errors.

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
	      Specifies	 a  pointer  to	 the  Display structure; returned from
	      XOpenDisplay.

       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  er-
       rors  are  returned, and	can be used to decode incoming event and error
       values.

       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.
