  69        These functions write the (null-terminated) character string <EM>str</EM> on the
  70        given  window.   It  is similar to calling <STRONG>waddch</STRONG> once for each byte in
  71        the string.
  72
  73        The <EM>mv</EM> functions perform  cursor  movement  once,  before  writing  any
  74        characters.   Thereafter,  the  cursor  is advanced as a side-effect of
  75        writing to the window.
  76
  77        The four functions with <EM>n</EM> as the last argument write at most  <EM>n</EM>  bytes,
  78        or  until  a  terminating null is reached.  If <EM>n</EM> is -1, then the entire
  79        string will be added.
  80
  81
  82 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  83        All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
  84
  85        X/Open does not  define  any  error  conditions.   This  implementation
  86        returns an error
  87
  88        <STRONG>o</STRONG>   if the window pointer is null or
  89
  90        <STRONG>o</STRONG>   if the string pointer is null or
  91
  92        <STRONG>o</STRONG>   if the corresponding calls to <STRONG>waddch</STRONG> return an error.
  93
  94        Functions  with  a  "mv"  prefix  first perform a cursor movement using
  95        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
  96        the  window  pointer is null.  If an error is returned by the <STRONG>wmove</STRONG>, no
  97        characters are added to the window.
  98
  99        If an error is returned by <STRONG>waddch</STRONG> (e.g.,  because  the  window  is  not
 100        large  enough,  or  an illegal byte sequence was detected) only part of
 101        the string may be added.  Aside from that, there is a special  case  in
 102        <STRONG>waddch</STRONG>  where  an  error  may  be returned after successfully writing a
 103        character to the lower-right corner of a window  when  <STRONG><A HREF="scrollok.3x.html">scrollok(3x)</A></STRONG>  is
 104        disabled.
