72 These functions return an array of complex characters in
73 <EM>wchstr</EM>, starting at the current cursor position in the
74 named window. Attributes (rendition) are stored with the
75 characters.
77 The <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG> and <STRONG>win_wchn-</STRONG>
78 <STRONG>str</STRONG> fill the array with at most <EM>n</EM> <STRONG>cchar_t</STRONG> elements.
81 </PRE>
82 <H2><a name="h2-NOTES">NOTES</a></H2><PRE>
83 Note that all routines except <STRONG>win_wchnstr</STRONG> may be macros.
85 Reading a line that overflows the array pointed to by <EM>wch-</EM>
86 <EM>str</EM> with <STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wch-</STRONG>
87 <STRONG>str</STRONG> causes undefined results. Therefore, the use of
88 <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG>, or <STRONG>win_wchnstr</STRONG> is
89 recommended.
92 </PRE>
93 <H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
94 Upon successful completion, these functions return <STRONG>OK</STRONG>.
95 Otherwise, they return <STRONG>ERR</STRONG>.
97 Functions with a "mv" prefix first perform a cursor move-
98 ment using <STRONG>wmove</STRONG>, and return an error if the position is
99 outside the window, or if the window pointer is null.

103 <H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
104 The XSI Curses defines no error conditions. This imple-
105 mentation checks for null pointers, returning ERR in that
106 case.
