70 <H2>DESCRIPTION</H2><PRE>
71        These  functions  write the characters of the (null-termi-
72        nated) <STRONG>wchar_t</STRONG> character string <EM>wstr</EM> on the given  window.
73        It  is  similar to constructing a <STRONG>cchar_t</STRONG> for each wchar_t
74        in the string, then calling  <STRONG>wadd_wch</STRONG>  for  the  resulting
75        <STRONG>cchar_t</STRONG>.
76
77        The  <EM>mv</EM>  functions  perform  cursor  movement once, before
78        writing any characters.  Thereafter,  the  cursor  is  ad-
79        vanced as a side-effect of writing to the window.
80
81        The  four  functions  with <EM>n</EM> as the last argument write at
82        most <EM>n</EM> <STRONG>wchar_t</STRONG> characters, or until a terminating null  is
83        reached.   If  <EM>n</EM>  is  -1,  then  the entire string will be
84        added.
85
86
87 </PRE>
88 <H2>RETURN VALUE</H2><PRE>
89        All functions return the integer <STRONG>ERR</STRONG> upon failure  and  <STRONG>OK</STRONG>
90        on success.
91
92        X/Open  does not define any error conditions.  This imple-
93        mentation returns an error
94
95        <STRONG>o</STRONG>   if the window pointer is null or
96
97        <STRONG>o</STRONG>   if the string pointer is null or
98
99        <STRONG>o</STRONG>   if the corresponding calls to <STRONG>wadd_wch</STRONG> return  an  er-
100            ror.
101
102        Functions  with a "mv" prefix first perform a cursor move-
103        ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
104        outside the window, or if the window pointer is null.
105
106
107 </PRE>
108 <H2>NOTES</H2><PRE>
109        All of these functions except <STRONG>waddnwstr</STRONG> may be macros.

112 </PRE>
113 <H2>PORTABILITY</H2><PRE>
114        These  functions are described in the XSI Curses standard,
115        Issue 4.
