       curs_scr_dump, scr_dump, scr_restore, scr_init, scr_set - read or write
       a curses screen from or to a file

       cc [ flag ... ] file ... -lcurses [ library ... ]
       #include <curses.h>

       int scr_dump(char *filename);

       int scr_restore(char *filename);

       int scr_init(char *filename);

       int scr_set(char *filename);

       With the scr_dump() routine, the current contents of the virtual screen
       are written to the file filename.

       With  the  scr_restore() routine, the virtual screen is set to the con‐
       tents of filename, which must have been written using  scr_dump().  The
       next call to doupdate() restores the screen to the way it looked in the
       dump file.

       With the scr_init() routine, the contents of filename are read  in  and
       used  to	 initialize the curses data structures about what the terminal
       currently has on its screen. If the data is  determined	to  be	valid,
       curses  bases  its next update of the screen on this information rather
       than clearing the screen and starting from scratch. scr_init() is  used
       after  initscr()	 or a system(3C) call to share the screen with another
       process which has done a scr_dump() after its endwin() call.  The  data
       is declared invalid if the time-stamp of the tty is old or the terminfo
       capabilities rmcup() and nrrmc() exist.

       The scr_set() routine is a combination of scr_restore() and scr_init().
       It  tells  the program that the information in filename is what is cur‐
       rently on the screen, and also what the program wants  on  the  screen.
       This can be thought of as a screen inheritance function.

       To  read	 (write)  a  window  from  (to)	 a  file, use the getwin() and
       putwin() routines (see curs_util(3CURSES)).

       All routines return the integer ERR upon failure and OK upon success.

       See attributes(5) for descriptions of the following attributes:

       The header <curses.h> automatically includes the headers	 <stdio.h> and

       Note that scr_init(), scr_set(), and scr_restore() may be macros.
