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

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