NAME
       curs_touch, is_linetouched, is_wintouched, touchline, touchwin, untouchwin, wtouchln - Curses routines that control refresh

SYNOPSIS
       #include <curses.h>

       bool is_linetouched(
	       WINDOW *win,
	       int line ); bool is_wintouched(
	       WINDOW *win ); int touchline(
	       WINDOW *win,
	       int start,
	       int count ); int touchwin(
	       WINDOW *win ); int untouchwin(
	       WINDOW *win ); int wtouchln(
	       WINDOW *win,
	       int y,
	       int n,
	       int changed );

LIBRARY
       Curses Library (libcurses)

DESCRIPTION
       The  touchwin and touchline routines throw away all optimization information about which parts of the window have been touched, by pretend-
       ing that the entire window has been drawn on. It is sometimes necessary to call these routines when using  overlapping  windows.   In  this
       case,  a  change to one window affects the other window, but the other window's records of which lines have been changed do not reflect the
       change in the first window. The touchline routine 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  (if	changed=1)  or	have  not  changed
       (changed=0) since the last call to wrefresh.

       The is_linetouched or is_wintouched routines return TRUE if the specified line or window was modified since the last call to wrefresh; oth-
       erwise they return FALSE. In addition, is_linetouched returns ERR if line is not valid for the given window.

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

       Note that touchline may be a macro.

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.
