DESCRIPTION

       A  main  window is a special kind of toplevel window used as the outer-
       most 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 interp->result.

       Tk_GetNumMainWindows returns a count of the number of main windows cur-
       rently open in the process.
