The scr_dump routine dumps the current contents of the virtual screen to the file 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 physical screen to the way it looked in the dump file. + +
The scr_init routine reads in the contents of filename and uses them 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 call to share the screen with another process which has - done a scr_dump after its endwin(3x) call.

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 @@ -124,7 +132,14 @@
