DESCRIPTION

151       This  implementation  can  be  configured to provide a set of functions
152       which improve the ability to manage multiple screens.  This feature can
153       be added to any of the configurations supported by ncurses; it adds new
154       entrypoints without changing the meaning of any of the existing ones.
155
156   IMPROVED FUNCTIONS
157       Most of the functions are new versions of existing functions.  A param‐
158       eter  is  added  at  the  front  of the parameter list.  It is a SCREEN
159       pointer.
160
161       The existing functions all use the current screen, which  is  a  static
162       variable.  The extended functions use the specified screen, thereby re‐
163       ducing the number of variables which must be modified to update  multi‐
164       ple screens.
165
166   NEW FUNCTIONS
167       Here are the new functions:
168
169       ceiling_panel
170            this returns a pointer to the topmost panel in the given screen.
171
172       ground_panel
173            this returns a pointer to the lowest panel in the given screen.
174
175       new_prescr
176            when  creating  a  new  screen,  the library uses static variables
177            which have been preset, e.g.,  by  use_env(3X),  filter(3X),  etc.
178            With  the  screen-pointer extension, there are situations where it
179            must create a current screen before the unextended  library  does.
180            The  new_prescr function is used internally to handle these cases.
181            It is also provided as an entrypoint to allow applications to cus‐
182            tomize the library initialization.
183

NOTES

185       This extension introduces some new names:
186
187       NCURSES_SP_FUNCS
188            This  is set to the library patch-level number.  In the unextended
189            library, this is zero (0), to make it useful for checking  if  the
190            extension is provided.
191
192       NCURSES_SP_NAME
193            The new functions are named using the macro NCURSES_SP_NAME, which
194            hides the actual implementation.  Currently this adds a "_sp" suf‐
195            fix  to the name of the unextended function.  This manual page in‐
196            dexes the extensions showing the full name.   However  the  proper
197            usage of these functions uses the macro, to provide for the possi‐
198            bility of changing the naming convention for specific library con‐
199            figurations.
200
201       NCURSES_SP_OUTC
202            This  is  a new function-pointer type to use in the screen-pointer
203            functions where an NCURSES_OUTC is used in the unextended library.
204
205       NCURSES_OUTC
206            This is a function-pointer type used for the cases where  a  func‐
207            tion passes characters to the output stream, e.g., vidputs(3X).
208

PORTABILITY

210       These  routines  are  specific  to ncurses.  They were not supported on
211       Version 7, BSD or System V implementations.  It is recommended that any
212       code  depending  on  ncurses  extensions  be  conditioned  using NCURS‐
213       ES_SP_FUNCS.
