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, otherwise
       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.
