69        These  functions  write the characters of the (null-terminated) <STRONG>wchar_t</STRONG>
70        character string <EM>wstr</EM> on the given window.  It is similar to construct-
71        ing a <STRONG>cchar_t</STRONG> for each wchar_t in the string, then calling <STRONG>wadd_wch</STRONG> for
72        the resulting <STRONG>cchar_t</STRONG>.
73
74        The <EM>mv</EM> functions perform cursor movement once, before writing any char-
75        acters.  Thereafter, the cursor is advanced as a side-effect of writing
76        to the window.
77
78        The four functions with <EM>n</EM> as the last argument write at most <EM>n</EM>  <STRONG>wchar_t</STRONG>
79        characters,  or  until a terminating null is reached.  If <EM>n</EM> is -1, then
80        the entire string will be added.
81
82
83 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
84        All functions return the integer <STRONG>ERR</STRONG> upon failure and <STRONG>OK</STRONG> on success.
85
86        X/Open does not define any error conditions.  This  implementation  re-
87        turns an error
88
89        <STRONG>o</STRONG>   if the window pointer is null or
90
91        <STRONG>o</STRONG>   if the string pointer is null or
92
93        <STRONG>o</STRONG>   if the corresponding calls to <STRONG>wadd_wch</STRONG> return an error.
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.
