DESCRIPTION


A main window is a special kind of toplevel window used as the
    outermost window in an application.


If interp is associated with a Tk application then
    Tk_MainWindow returns the application's main window. If there is no
    Tk application associated with interp then Tk_MainWindow
    returns NULL and leaves an error message in interpreter interp's
    result.


Tk_GetNumMainWindows returns a count of the number of main
    windows currently open in the current thread.
