NAME

       curs_touch, touchwin, touchline, untouchwin, wtouchln, is_linetouched, is_wintouched - curses refresh control routines

SYNOPSIS

       cc [ flag ... ] file ... -lcurses [ library ... ]
       #include <curses.h>

       int touchwin(WINDOW *win);

       int touchline(WINDOW *win, int start, int count);

       int untouchwin(WINDOW *win);

       int wtouchln(WINDOW *win, int y, int n, int changed);

       int is_linetouched(WINDOW *win, int line);

       int is_wintouched(WINDOW *win);

DESCRIPTION

       The  touchwin() and touchline() routines throw away all optimization information about which parts of the window have been touched, by pre-
       tending that the entire window has been drawn on. This is sometimes necessary when using overlapping windows, since a change to one  window
       affects	the  other  window,  but  the  records of which lines have been changed in the other window do not reflect the change. The routine
       touchline() only pretends that count lines have been changed, beginning with line start.

       The untouchwin() routine marks all lines in the window as unchanged since the last call to wrefresh().

       The wtouchln() routine makes n lines in the window, starting at line y, look as if they have  (changed=1)  or  have  not  (changed=0)  been
       changed since the last call to wrefresh().

       The  is_linetouched() and is_wintouched() routines return TRUE if the specified line/window was modified since the last call to wrefresh();
       otherwise they return FALSE. In addition, is_linetouched() returns ERR if line is not valid for the given window.

RETURN VALUES

       All routines return the integer ERR upon failure and an integer value other than ERR upon successful completion, unless otherwise noted	in
       the preceding routine descriptions.
