  69        These functions copy the (null-terminated) <EM>chstr</EM> array into the  window
  70        image  structure  starting  at  the  current cursor position.  The four
  71        functions with <EM>n</EM> as the last argument copy at most <EM>n</EM> elements,  but  no
  72        more  than  will  fit  on  the  line.   If <STRONG>n</STRONG>=<STRONG>-1</STRONG> then the whole array is
  73        copied, to the maximum number of characters that will fit on the line.
  74
  75        The window cursor is <EM>not</EM> advanced.  These functions  work  faster  than
  76        <STRONG>waddnstr</STRONG>.  On the other hand:
  77
  78        <STRONG>o</STRONG>   they  do  not perform checking (such as for the newline, backspace,
  79            or carriage return characters),
  80
  81        <STRONG>o</STRONG>   they do not advance the current cursor position,
  82
  83        <STRONG>o</STRONG>   they do not expand other control characters to ^-escapes, and
  84
  85        <STRONG>o</STRONG>   they truncate the string if it crosses  the  right  margin,  rather
  86            than wrapping it around to the new line.
  87

  89 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  90        All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
  91
  92        X/Open  does  not  define  any  error  conditions.  This implementation
  93        returns an error if the window pointer is null.
  94
  95        Functions with a "mv" prefix first  perform  a  cursor  movement  using
  96        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
  97        the window pointer is null.
