.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.
