65 These functions extract the complex character and rendition from the
66 current position in the named window into the <STRONG>cchar_t</STRONG> object referenced
70 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
71 No errors are defined in the XSI Curses standard. This implementation
72 checks for null pointers, returns <STRONG>ERR</STRONG> in that case. Also, the <EM>mv</EM>
73 routines check for error moving the cursor, returning <STRONG>ERR</STRONG> in that case.
74 Otherwise they return <STRONG>OK</STRONG>.
76 Functions with a "mv" prefix first perform a cursor movement using
77 <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
78 the window pointer is null.
