68        These  functions  write the characters of the (null-termi-
69        nated) <STRONG>wchar_t</STRONG> character string <EM>wstr</EM> on the given  window.
70        It  is  similar to constructing a <STRONG>cchar_t</STRONG> for each wchar_t
71        in the string, then calling  <STRONG>wadd_wch</STRONG>  for  the  resulting
72        <STRONG>cchar_t</STRONG>.
73
74        The  <EM>mv</EM>  functions  perform  cursor  movement once, before
75        writing any characters.  Thereafter,  the  cursor  is  ad-
76        vanced as a side-effect of writing to the window.
77
78        The  four  functions  with <EM>n</EM> as the last argument write at
79        most <EM>n</EM> <STRONG>wchar_t</STRONG> characters, or until a terminating null  is
80        reached.   If  <EM>n</EM>  is  -1,  then  the entire string will be
81        added.
82
83
84 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
85        All functions return the integer <STRONG>ERR</STRONG> upon failure  and  <STRONG>OK</STRONG>
86        on success.
87
88        X/Open  does not define any error conditions.  This imple-
89        mentation returns an error
90
91        <STRONG>o</STRONG>   if the window pointer is null or
92
93        <STRONG>o</STRONG>   if the string pointer is null or
94
95        <STRONG>o</STRONG>   if the corresponding calls to <STRONG>wadd_wch</STRONG> return  an  er-
96            ror.
97
98        Functions  with a "mv" prefix first perform a cursor move-
99        ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
100        outside the window, or if the window pointer is null.

104        All of these functions except <STRONG>waddnwstr</STRONG> may be macros.

108        These  functions are described in the XSI Curses standard,
109        Issue 4.
