CURSES_TOUCH(3) 					   BSD Library Functions Manual 					   CURSES_TOUCH(3)

NAME

     curses_touch, touchline, touchoverlap, touchwin, untouchwin, wtouchln, is_linetouched, is_wintouched, redrawwin, wredrawln, wsyncup,
     wsyncdown -- curses window modification routines

LIBRARY

     Curses Library (libcurses, -lcurses)

SYNOPSIS

     #include <curses.h>

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

     int
     touchoverlap(WINDOW *win1, WINDOW *win2);

     int
     touchwin(WINDOW *win);

     int
     untouchwin(WINDOW *win);

     int
     wtouchln(WINDOW *win, int line, int n, boolf changed);

     bool
     is_linetouched(WINDOW *win, int line);

     bool
     is_wintouched(WINDOW *win);

     int
     redrawwin(WINDOW *win);

     int
     wredrawln(WINDOW *win, int line, int n);

     void
     wsyncup(WINDOW *win);

     void
     wsyncdown(WINDOW *win);

DESCRIPTION

     These functions mark lines and windows as modified and check the modification status of lines and windows.

     The touchline() function marks count lines starting from start in window win as having been modified.  These characters will be synced to the
     terminal on the next call to wrefresh().

     The touchoverlap() function marks the portion of win2 that overlaps win1 as being modified.

     The touchwin() function marks the entire window win as having been modified.  Conversely, the untouchwin() function marks the window win as
     being unmodified, so that any changes made to that window will not be synced to the terminal during a wrefresh().

     The wtouchln() function performs one of two operations on n lines starting at line in the given window.  If changed is 1 then the given line
     range is marked as being modified, if changed is 0 then the given line range is set to being unmodified.

     The is_linetouched() function returns TRUE if line in window win has been modified since the last refresh was done, otherwise FALSE is
     returned.

     is_wintouched() returns TRUE if the window win has been modified since the last refresh, otherwise FALSE is returned.

     The redrawwin() function marks the entire window win as having been corrupted.  Is is equivalent to the touchwin() function.

     The wredrawln() function marks n lines starting at line in the given window as corrupted.	It is equivalent to wtouchln(win, line, n, 1).

     The wsyncup() function touches all ancestors of win.

     The wsyncdown() function touches win if any of its ancestors is touched.

RETURN VALUES

     Functions returning pointers will return NULL if an error is detected.  The functions that return an int will return one of the following
     values:

     OK   The function completed successfully.
     ERR  An error occurred in the function.

SEE ALSO

     curses_refresh(3)

STANDARDS

     The NetBSD Curses library complies with the X/Open Curses specification, part of the Single Unix Specification.

HISTORY

     The Curses package appeared in 4.0BSD.
