73        These functions return an array of complex  characters  in
74        <EM>wchstr</EM>,  starting  at  the  current cursor position in the
75        named window.  Attributes (rendition) are stored with  the
76        characters.
77
78        The  <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG> and <STRONG>win_wchn-</STRONG>
79        <STRONG>str</STRONG> fill the array with at most <EM>n</EM> <STRONG>cchar_t</STRONG> elements.

84        Note that all routines except <STRONG>win_wchnstr</STRONG> may be macros.
85
86        Reading a line that overflows the array pointed to by <EM>wch-</EM>
87        <EM>str</EM>  with <STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wch-</STRONG>
88        <STRONG>str</STRONG>  causes  undefined  results.  Therefore,  the  use  of
89        <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG>, or <STRONG>win_wchnstr</STRONG> is
90        recommended.

94 <H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
95        Upon successful completion,  these  functions  return  <STRONG>OK</STRONG>.
96        Otherwise, they return <STRONG>ERR</STRONG>.
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.

105        The  XSI  Curses defines no error conditions.  This imple-
106        mentation checks for null pointers, returning ERR in  that
107        case.
