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.
