</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></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 four functions with <EM>n</EM> as the last argument return a leading
substring at most <EM>n</EM> characters long (exclusive of the trailing zeroed
<STRONG>cchar_t</STRONG>. Transfer stops at the end of the current line, or when <EM>n</EM>
characters have been stored at the location referenced by <EM>wchstr</EM>.
Constants defined in <STRONG><curses.h></STRONG> can be used with the <STRONG>&</STRONG> (logical AND)
operator to extract the character or the attribute alone from any
position in the <EM>wchstr</EM> [see <STRONG><A HREF="curs_getcchar.3x.html">getcchar(3x)</A></STRONG>].
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
Upon successful completion, these functions return <STRONG>OK</STRONG>. Otherwise, they
return <STRONG>ERR</STRONG>.
X/Open Curses defines no error conditions. This implementation returns
an error
<STRONG>o</STRONG> if the <EM>win</EM> parameter is null or
<STRONG>o</STRONG> if the <EM>wchstr</EM> parameter is null.
Functions prefixed with "mv" first perform cursor movement and fail if
the position (<EM>y</EM>, <EM>x</EM>) is outside the window boundaries.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
All routines except <STRONG>win_wchnstr</STRONG> may be macros.
Reading a line that overflows the array pointed to by <EM>wchstr</EM> with
<STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wchstr</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.

X/Open Curses defines no error conditions. This implementation checks
for null pointers, returning <STRONG>ERR</STRONG> in that case.
