</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
These functions extract the complex character and rendition from the
current position in the named window into the <STRONG>cchar_t</STRONG> object referenced
by wcval.
</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
No errors are defined in the XSI Curses standard. This implementation
checks for null pointers, returns <STRONG>ERR</STRONG> in that case. Also, the <EM>mv</EM> rou-
tines check for error moving the cursor, returning <STRONG>ERR</STRONG> in that case.
Otherwise they return <STRONG>OK</STRONG>.
Functions with a "mv" prefix first perform a cursor movement using
<STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
the window pointer is null.
</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
Note that all of these routines may be macros.
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
These functions are described in the XSI Curses standard, Issue 4.
