DESCRIPTION

       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 configu-
       rations supported by  ncurses;  it  adds  new  entrypoints
       without changing the meaning of any of the existing ones.

   IMPROVED FUNCTIONS
       Most  of  the functions are new versions of existing func-
       tions.  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.

   NEW FUNCTIONS
       Here are the new functions:

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

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

       new_prescr
            when creating a new screen, the library  uses  static
            variables   which   have   been   preset,   e.g.,  by
            curs_util(3x), curs_util(3x), etc.  With the screen-point-
            er extension, there are situations where it must cre-
            ate 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 entry-
            point  to allow applications to customize the library
            initialization.


NOTES

       This extension introduces some new names:

       NCURSES_SP_FUNCS
            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.

       NCURSES_SP_NAME
            The new functions are named using  the  macro  NCURS-
            ES_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.

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

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


PORTABILITY

       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 ex-
       tensions be conditioned using NCURSES_SP_FUNCS.
