67 <H2>DESCRIPTION</H2><PRE>
68        These functions return an array of complex  characters  in
69        <EM>wchstr</EM>,  starting  at  the  current cursor position in the
70        named window.  Attributes (rendition) are stored with  the
71        characters.
72
73        The  <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG> and <STRONG>win_wchn-</STRONG>
74        <STRONG>str</STRONG> fill the array with at most <EM>n</EM> <STRONG>cchar_t</STRONG> elements.
75
76
77 </PRE>
78 <H2>NOTES</H2><PRE>
79        Note that all routines except <STRONG>win_wchnstr</STRONG> may be macros.
80
81        Reading a line that overflows the array pointed to by <EM>wch-</EM>
82        <EM>str</EM>  with <STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wch-</STRONG>
83        <STRONG>str</STRONG>  causes  undefined  results.  Therefore,  the  use  of
84        <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG>, or <STRONG>win_wchnstr</STRONG> is
85        recommended.
86
87
88 </PRE>
89 <H2>RETURN VALUES</H2><PRE>
90        Upon successful completion,  these  functions  return  <STRONG>OK</STRONG>.
91        Otherwise, they return <STRONG>ERR</STRONG>.
92
93
94 </PRE>
95 <H2>PORTABILITY</H2><PRE>
96        The  XSI  Curses defines no error conditions.  This imple-
97        mentation checks for null pointers, returning ERR in  that
98        case.
