XpQueryVersion(3Xp)                           XPRINT FUNCTIONS                           XpQueryVersion(3Xp)



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.
