  70        These  functions copy the (null-terminated) array of complex characters
  71        <EM>wchstr</EM> into the window image structure starting at the  current  cursor
  72        position.   The four functions with <EM>n</EM> as the last argument copy at most
  73        <EM>n</EM> elements, but no more than will fit on the line.  If  <STRONG>n</STRONG>=<STRONG>-1</STRONG>  then  the
  74        whole  array  is  copied, to the maximum number of characters that will
  75        fit on the line.
  76
  77        The window cursor is <EM>not</EM> advanced.  These functions  work  faster  than
  78        <STRONG>waddnstr</STRONG>.  On the other hand:
  79
  80        <STRONG>o</STRONG>   they  do  not perform checking (such as for the newline, backspace,
  81            or carriage return characters),
  82
  83        <STRONG>o</STRONG>   they do not advance the current cursor position,
  84
  85        <STRONG>o</STRONG>   they do not expand other control characters to ^-escapes, and
  86
  87        <STRONG>o</STRONG>   they truncate the string if it crosses  the  right  margin,  rather
  88            than wrapping it around to the new line.
  89
  90        These  functions  end  successfully  on encountering a null <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>, or
  91        when they have filled the current line.  If a complex character  cannot
  92        completely  fit  at  the end of the current line, the remaining columns
  93        are filled with the background character and rendition.
  94
  95
  96 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  97        All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
  98
  99        X/Open does not define any error conditions.  This  implementation  re-
 100        turns an error if the window pointer is null.
 101
 102        Functions  with  a  "mv"  prefix  first perform a cursor movement using
 103        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
 104        the window pointer is null.
