printf("test\n");
then it appears properly on screen.
but what if i don't want to use \n ?
and also, the new bash line should appear _next to_ my data, but should not
overwrite it! i would like to know why...

scr_restore
curs_scr_dump(3X) curs_scr_dump(3X)
NAME
scr_dump, scr_restore, scr_init, scr_set - read (write) a curses screen from (to) a file
SYNOPSIS
#include <curses.h>
int scr_dump(const char *filename);
int scr_restore(const char *filename);
int scr_init(const char *filename);
int scr_set(const char *filename);
DESCRIPTION
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 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 cur-
rently 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 [see system(BA_LIB)] 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 terminfo capabilities
rmcup and nrrmc exist; also if the terminal has been written to since the preceding scr_dump 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 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(3X)].
RETURN VALUE
All routines return the integer ERR upon failure and OK upon success.
NOTES
Note that scr_init, scr_set, and scr_restore may be macros.
PORTABILITY
The XSI Curses standard, Issue 4, describes these functions (adding the const qualifiers).
The SVr4 docs merely say under scr_init that the dump data is also considered invalid "if the time-stamp of the tty is old" but don't
define "old".
