NAME
       curs_scr_dump, scr_dump, scr_init, scr_restore, scr_set - Read or write
       a Curses screen from or to a file

SYNOPSIS
       #include <curses.h>

       int scr_dump(
	       const char *filename ); int scr_init(
	       const char *filename ); int scr_restore(
	       const char *filename ); int scr_set(
	       const char *filename );

LIBRARY
       Curses Library (libcurses)

STANDARDS
       Interfaces documented on this reference page conform to industry	 stan‐
       dards as follows:

       scr_dump, scr_init, scr_restore, scr_set:  XCURSES4.2

       Refer  to  the  standards(5)  reference page for more information about
       industry standards and associated tags.

DESCRIPTION
       The scr_dump routine writes the current contents of the virtual	screen
       to filename.

       The  scr_restore	 routine  sets	the  virtual screen to the contents 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.

       The  scr_init routine reads the content of filename and uses it to ini‐
       tialize the Curses data structures that describe what the terminal cur‐
       rently  has on its screen. If Curses determines that the data is valid,
       it bases its next update of the screen on this data rather than	clear‐
       ing  the	 screen	 and starting from scratch. Applications call scr_init
       after an initscr or a system call (see system(3)) to share  the	screen
       with  another  process  that  executed  scr_dump	 after	endwin. Curses
       declares the data 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. This
       routine tells the program that the information in filename is  what  is
       currently  on  the  screen and is what the program wants on the screen.
       The scr_set routine can be thought of as a screen-inheritance function.

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

NOTES
       The  header  file  <curses.h>  automatically  includes  the header file
       <stdio.h>.

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