XFetchName(3)


NAME

   XSetWMName, XGetWMName, XStoreName, XFetchName - set or read a window's
   WM_NAME property

SYNTAX

   void XSetWMName(Display *display, Window w, XTextProperty *text_prop);

   Status XGetWMName(Display *display, Window w, XTextProperty
          *text_prop_return);

   int XStoreName(Display *display, Window w, char *window_name);

   Status XFetchName(Display *display, Window w, 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.
