curs_scr_dump(3) Library Functions Manual curs_scr_dump(3) 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 standards 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 initialize the Curses data structures that describe what the terminal currently 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 clearing 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. SEE ALSO

curs_scr_dump, scr_dump, scr_restore, scr_init, scr_set - read or write a curses screen from or to a file SYNOPSIS
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); DESCRIPTION
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 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. 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 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 curs_util(3CURSES)). RETURN VALUES
All routines return the integer ERR upon failure and OK upon success. ATTRIBUTES
