<H2>DESCRIPTION</H2><PRE>
These functions return an array of complex characters in
<EM>wchstr</EM>, starting at the current cursor position in the
named window. Attributes (rendition) are stored with the
characters.
The <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG> and <STRONG>win_wchn-</STRONG>
<STRONG>str</STRONG> fill the array with at most <EM>n</EM> <STRONG>cchar_t</STRONG> elements.
</PRE>
<H2>NOTES</H2><PRE>
Note that all routines except <STRONG>win_wchnstr</STRONG> may be macros.
Reading a line that overflows the array pointed to by <EM>wch-</EM>
<EM>str</EM> with <STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wch-</STRONG>
<STRONG>str</STRONG> causes undefined results. Therefore, the use of
<STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG>, or <STRONG>win_wchnstr</STRONG> is
recommended.
</PRE>
<H2>RETURN VALUE</H2><PRE>
Upon successful completion, these functions return <STRONG>OK</STRONG>.
Otherwise, they return <STRONG>ERR</STRONG>.
Functions with a "mv" prefix first perform a cursor move-
ment using <STRONG>wmove</STRONG>, and return an error if the position is
outside the window, or if the window pointer is null.
</PRE>
<H2>PORTABILITY</H2><PRE>
The XSI Curses defines no error conditions. This imple-
mentation checks for null pointers, returning ERR in that
case.
