curs_touch(3)
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)

STANDARDS
  Interfaces documented on this reference page conform to industry standards
  as follows:

  is_linetouched, is_wintouched, touchline, touchwin, untouchwin,
  wtouchln:  XCURSES4.2

  Refer to the standards(5) reference page for more information about
  industry standards and associated tags.

DESCRIPTION
  The touchwin and touchline routines throw away all optimization information
  about which parts of the window have been touched, by pretending 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; otherwise 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.
