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.
