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
       associated 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
       errors 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.
