-       mization  information about which parts of the window have
-       been touched, by pretending 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.

-       Some historic curses implementations had,  as  an  undocu-
-       mented  feature,  the  ability  to  do  the  equivalent of
-       <STRONG>clearok(...,</STRONG> <STRONG>1)</STRONG> by saying <STRONG>touchwin(stdscr)</STRONG>  or  <STRONG>clear(std-</STRONG>
-       <STRONG>scr)</STRONG>.  This will not work under ncurses.

+               normal return values of this function.   Because  the  function
+               returns a <STRONG>bool</STRONG>, returning <STRONG>ERR</STRONG> (which is neither <STRONG>TRUE</STRONG> nor <STRONG>FALSE</STRONG>)
+               may not be supported by the compiler.
 
 
+               To provide error-checking and also match  the  X/Open  function
+               prototype, the <STRONG>ERR</STRONG> is provided by a macro named <STRONG>is_linetouched</STRONG>.
+               The actual function returns <STRONG>FALSE</STRONG> when it detects an error.
