       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 *text_prop_return);

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

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


       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 string.

                 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; 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.


       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.
