<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>.
