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 

       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  num-
       bers 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.
