XSetWMName(3)			XLIB FUNCTIONS			 XSetWMName(3)

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

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

       Status XGetWMName(Display *display, Window w, XTextProperty

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

       Status XFetchName(Display *display, Window w, char **win‐

       display	 Specifies the connection to the X server.

       text_prop Specifies the XTextProperty structure to be used.

		 Returns the XTextProperty structure.

       w	 Specifies the window.

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

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

       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; other‐
       wise, 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 win‐
       dows 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-

       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

       XFetchName can generate a BadWindow error.

       WM_NAME	 The name of the application.

       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.
