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 configurations 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 functions.  A param-
       eter  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 re-
       ducing the number of variables which must be modified to update  multi-
       ple 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  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 cus-
            tomize 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 NCURSES_SP_NAME, which
            hides the actual implementation.  Currently this adds a "_sp" suf-
            fix  to the name of the unextended function.  This manual page in-
            dexes the extensions showing the full name.   However  the  proper
            usage of these functions uses the macro, to provide for the possi-
            bility of changing the naming convention for specific library con-
            figurations.

       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  func-
            tion passes characters to the output stream, e.g., vidputs(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  extensions  be  conditioned  using NCURS-
       ES_SP_FUNCS.
