  69        These functions copy the (null-terminated) array  of  com-
  70        plex  characters  <EM>wchstr</EM>  into  the window image structure
  71        starting at the current cursor position.  The  four  func-
  72        tions with <EM>n</EM> as the last argument copy at most <EM>n</EM> elements,
  73        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
  75        that will fit on the line.
  76
  77        The window cursor is <EM>not</EM> advanced.  These  functions  work
  78        faster than <STRONG>waddnstr</STRONG>.  On the other hand:
  79
  80        <STRONG>o</STRONG>   they do not perform checking (such as for the newline,
  81            backspace, 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  ^-es-
  86            capes, and
  87
  88        <STRONG>o</STRONG>   they  truncate the string if it crosses the right mar-
  89            gin, rather than wrapping it around to the new line.
  90
  91        These functions end successfully on  encountering  a  null
  92        <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>,  or when they have filled the current line.  If a
  93        complex character cannot completely fit at the end of  the
  94        current  line,  the  remaining columns are filled with the
  95        background character and rendition.

  98 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  99        All functions return the integer <STRONG>ERR</STRONG> upon failure  and  <STRONG>OK</STRONG>
 100        on success.
 101
 102        X/Open  does not define any error conditions.  This imple-
 103        mentation returns an error if the window pointer is null.
 104
 105        Functions with a "mv" prefix first perform a cursor  move-
 106        ment  using  <STRONG>wmove</STRONG>, and return an error if the position is
 107        outside the window, or if the window pointer is null.
