curs_scr_dump(3X)                UNIX System V                curs_scr_dump(3X)


NAME
      cursscrdump:  scrdump, scrrestore, scrinit, scrset - read (write) a
      curses screen from (to) a file

SYNOPSIS
      #include <curses.h>

      int scrdump(char *filename);
      int scrrestore(char *filename);
      int scrinit(char *filename);
      int scrset(char *filename);

DESCRIPTION
      With the scrdump routine, the current contents of the virtual screen are
      written to the file filename.

      With the scrrestore routine, the virtual screen is set to the contents
      of filename, which must have been written using scrdump.  The next call
      to doupdate restores the screen to the way it looked in the dump file.

      With the scrinit 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.  scrinit is used
      after initscr or a system [see system(BA_LIB)] call to share the screen
      with another process which has done a scrdump 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 scrset routine is a combination of scrrestore and scrinit.  It
      tells the program that the information in filename is what is currently
      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 cursutil(3X)].

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

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

      Note that scrinit, scrset, and scrrestore may be macros.
