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.
