NAME
       XpQueryVersion  -  Queries  an  X  Server to determine if it supports the X Print Service Extension, and if it does, which version of the X
       Print Service Extension.

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

       Status XpQueryVersion ( display, major_version_return, minor_version_return )
	     Display *display;
	     short *major_version_return;
	     short *minor_version_return;

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

       major_version_return
	      Returns the major version if the X Print Service Extension exists, else zero.

       minor_version_return
	      Returns the minor version if the X Print Service Extension exists, else zero.

DESCRIPTION
       XpQueryVersion determines if the X Print Service Extension is present. A non-zero Status is returned if the extension is supported,  other-
       wise  a zero Status is returned. If the extension is supported, the major and minor version numbers are returned to indicate the level of X
       Print Service Extension support.

       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.
