       This  implementation  can  be  configured  to provide a set of functions which improve the
       ability  to  manage  multiple  screens.   This  feature  can  be  added  to  any  of   the
       configurations  supported by ncurses; it adds new entrypoints without changing the meaning
       of any of the existing ones.

       Most of the functions are new versions of existing functions.  A parameter is added at the
       front of the parameter list.  It is a SCREEN pointer.

       The  existing  functions  all  use  the  current  screen, which is a static variable.  The
       extended functions use the specified screen, thereby  reducing  the  number  of  variables
       which must be modified to update multiple screens.

       Here are the new functions:

            this returns a pointer to the topmost panel in the given screen.

            this returns a pointer to the lowest panel in the given screen.

            when creating a new screen, the library uses static variables which have been preset,
            e.g., by use_env(3X), filter(3X), etc.  With the screen-pointer extension, there  are
            situations  where it must create a current screen before the unextended library does.
            The new_prescr function is used  internally  to  handle  these  cases.   It  is  also
            provided   as   an   entrypoint  to  allow  applications  to  customize  the  library


       This extension introduces some new names:

            This is set to the library patch-level number.  In the unextended  library,  this  is
            zero (0), to make it useful for checking if the extension is provided.

            The  new  functions are named using the macro NCURSES_SP_NAME, which hides the actual
            implementation.  Currently this adds a "_sp" suffix to the  name  of  the  unextended
            function.   This  manual  page indexes the extensions showing the full name.  However
            the proper usage of these functions uses the macro, to provide for the possibility of
            changing the naming convention for specific library configurations.

            This  is  a new function-pointer type to use in the screen-pointer functions where an
            NCURSES_OUTC is used in the unextended library.

            This is a function-pointer type used for the cases where a function passes characters
            to the output stream, e.g., vidputs(3X).


       These  routines  are  specific  to  ncurses.  They were not supported on Version 7, BSD or
       System V implementations.  It is recommended that any code depending on ncurses extensions
       be conditioned using NCURSES_SP_FUNCS.
