+.SH 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.
+.PP
+.\" ***************************************************************************
+.SS IMPROVED FUNCTIONS
+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.
+.PP
+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.
+.\" ***************************************************************************
+.SS NEW FUNCTIONS
+Here are the new functions:
+.TP 5
+ceiling_panel
+this returns a pointer to the topmost panel in the given screen.
+.TP 5
+ground_panel
+this returns a pointer to the lowest panel in the given screen.
+.TP 5
+new_prescr
+when creating a new screen, the library uses static variables which
+have been preset, e.g., by \fBuse_env\fP(3X), \fBfilter\fP(3X), etc.
+With the screen-pointer extension,
+there are situations where it must create a current screen before
+the unextended library does.
+The \fBnew_prescr\fP function is used internally to handle these cases.
+It is also provided as an entrypoint to allow applications to customize
+the library initialization.
+.\" ***************************************************************************
+.SH NOTES
+This extension introduces some new names:
+.TP 5
+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.
+.TP 5
+NCURSES_SP_NAME
+The new functions are named using the macro \fINCURSES_SP_NAME\fP,
+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.
+.TP 5
+NCURSES_SP_OUTC
+This is a new function-pointer type to use in the screen-pointer functions
+where an \fINCURSES_OUTC\fP is used in the unextended library.
+.TP 5
+NCURSES_OUTC
+This is a function-pointer type used for the cases where a function passes
+characters to the output stream, e.g., \fBvidputs\fP(3X).
+.PP
+.SH 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 \fINCURSES_SP_FUNCS\fP.
