          Status XFetchName(display, w, window_name_return)
                Display *display;

                char **window_name_return;

     ARGUMENTS
          display   Specifies the connection to the X server.

          text_prop Specifies the XTextProperty structure to be used.

          text_prop_return
                    Returns the XTextProperty structure.

          w         Specifies the window.

          window_name
                    Specifies the window name, which should be a
                    null-terminated string.

          window_name_return
                    Returns the window name, which is a null-
                    terminated string.

     DESCRIPTION
          The XSetWMName convenience function calls XSetTextProperty
          to set the WM_NAME property.

          The XGetWMName convenience function calls XGetTextProperty
          to obtain the WM_NAME property.  It returns a nonzero status
          on success; otherwise, it returns a zero status.

          The XStoreName function assigns the name passed to
          window_name to the specified window.  A window manager can
          display the window name in some prominent place, such as the
          title bar, to allow users to identify windows easily.  Some
          window managers may display a window's name in the window's
          icon, although they are encouraged to use the window's icon
          name if one is provided by the application.  If the string
          is not in the Host Portable Character Encoding, the result
          is implementation-dependent.

          XStoreName can generate BadAlloc and BadWindow errors.

          The XFetchName function returns the name of the specified
          window.  If it succeeds, it returns a nonzero status;
          otherwise, no name has been set for the window, and it
          returns zero.  If the WM_NAME property has not been set for
          this window, XFetchName sets window_name_return to NULL.  If
          the data returned by the server is in the Latin Portable
          Character Encoding, then the returned string is in the Host
          Portable Character Encoding.  Otherwise, the result is
          implementation-dependent.  When finished with it, a client
          must free the window name string using XFree.

          XFetchName can generate a BadWindow error.

     PROPERTIES
          WM_NAME   The name of the application.

     DIAGNOSTICS
          BadAlloc  The server failed to allocate the requested
                    resource or server memory.

          BadWindow A value for a Window argument does not name a
                    defined Window.
