NAME

       Tk_MainWindow,  Tk_GetNumMainWindows - functions for querying main win-
       dow information


SYNOPSIS

       #include <tk.h>

       Tk_Window
       Tk_MainWindow(interp)

       int
       Tk_GetNumMainWindows()



ARGUMENTS

       Interpreter associated with the application.



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.
