XGetZoomHints() 														   XGetZoomHints()

Name
  XGetZoomHints - read the size hints property of a zoomed window.

Synopsis
  Status XGetZoomHints(display, w, zhints_return)
	Display *display;
	Window w;
	XSizeHints *zhints_return;

Arguments
  display  Specifies a connection to an X server; returned from XOpenDisplay().

  w	   Specifies the ID of the window to be queried.

  zhints_return
	   Returns a pointer to the zoom hints.

Returns
  Zero on failure, non-zero on success.

Description
  XGetZoomHints() is obsolete beginning in Release 4, because zoom hints are no longer defined in the ICCCM.

  XGetZoomHints()  is  primarily for window managers.  XGetZoomHints() returns the size hints for a window in its zoomed state (not normal or
  iconified) read from the XA_WM_ZOOM_HINTS property.  It returns a non-zero Status if it succeeds, and zero if the application did not spec-
  ify zoom size hints for this window.

  For more information on using hints, see Volume One, Chapter 12, Interclient Communication.
