+<H2>DESCRIPTION</H2><PRE>
+ The <STRONG>getcchar</STRONG> function gets a wide-character string and
+ rendition from a <STRONG>cchar_t</STRONG> argument. When <EM>wch</EM> is not a null
+ pointer, the <STRONG>getcchar</STRONG> function does the following:
+
+ - Extracts information from a <STRONG>cchar_t</STRONG> value <EM>wcval</EM>
+
+ - Stores the character attributes in the location
+ pointed to by <EM>attrs</EM>
+
+ - Stores the color-pair in the location pointed to by
+ <EM>color</EM><STRONG>_</STRONG><EM>pair</EM>
+
+ - Stores the wide-character string, characters refer-
+ enced by <EM>wcval</EM>, into the array pointed to by <EM>wch</EM>.
+
+ When <EM>wch</EM> is a null pointer, the <STRONG>getcchar</STRONG> function does the
+ following:
+
+ - Obtains the number of wide characters pointed to by
+ <EM>wcval</EM>
+
+ - Does not change the data referenced by <EM>attrs</EM> or
+ <EM>color</EM><STRONG>_</STRONG><EM>pair</EM>
+
+ The <STRONG>setcchar</STRONG> function initializes the location pointed to
+ by <EM>wcval</EM> by using:
+
+ - The character attributes in <EM>attrs</EM>
+
+ - The color pair in <EM>color</EM><STRONG>_</STRONG><EM>pair</EM>
+
+ - The wide-character string pointed to by <EM>wch</EM>. The
+ string must be L'\0' terminated, contain at most one
+ spacing character, which must be the first.
+
+ Up to <STRONG>CCHARW_MAX</STRONG>-1 nonspacing characters may follow.
+ Additional nonspacing characters are ignored.
+
+ The string may contain a single control character
+ instead. In that case, no nonspacing characters are
+ allowed.
+
+
+</PRE>
+<H2>NOTES</H2><PRE>
+ The <EM>opts</EM> argument is reserved for future use. Currently,
+ an application must provide a null pointer as <EM>opts</EM>.
+
+ The <EM>wcval</EM> argument may be a value generated by a call to
+ <STRONG>setcchar</STRONG> or by a function that has a <STRONG>cchar_t</STRONG> output argu-
+ ment. If <EM>wcval</EM> is constructed by any other means, the
+ effect is unspecified.
+
+
+</PRE>
+<H2>RETURN VALUES</H2><PRE>
+ When <EM>wch</EM> is a null pointer, <STRONG>getcchar</STRONG> returns the number of
+ wide characters referenced by <EM>wcval</EM>.
+
+ When <EM>wch</EM> is not a null pointer, <STRONG>getcchar</STRONG> returns <STRONG>OK</STRONG> upon
+ successful completion, and <STRONG>ERR</STRONG> otherwise.
+
+ Upon successful completion, <STRONG>setcchar</STRONG> returns <STRONG>OK</STRONG>. Other-
+ wise, it returns <STRONG>ERR</STRONG>.
