       getcchar,  setcchar  - Get a wide character string and rendition from a
       cchar_t or set a cchar_t from a wide-character string

       #include <curses.h>

       int getcchar(
	       const cchar_t *wcval,
	       wchar_t *wch,
	       attr_t *attrs,
	       short *color_pair,
	       void *opts );

       int setcchar(
	       cchar_t *wcval,
	       const wchar_t *wch,
	       const attr_t attrs,
	       short color_pair,
	       void *opts );

       The getcchar function gets a wide-character string and rendition from a
       cchar_t	argument.   When wch is not a null pointer, the getcchar func‐
       tion does the following:

       -    Extracts information from a cchar_t value wcval

       -    Stores the character attributes in	the  location  pointed	to  by

       -    Stores the color-pair in the location pointed to by color_pair

       -    Stores  the wide-character string, characters referenced by wcval,
	    into the array pointed to by wch.

       When wch is a null pointer, the getcchar function does the following:

       -    Obtains the number of wide characters pointed to by wcval

       -    Does not change the data referenced by attrs or color_pair

       The setcchar function initializes the location pointed to by  wcval  by

       -    The character attributes in attrs

       -    The color pair in color_pair

       -    The	 wide-character	 string pointed to by wch.  The string must be
	    L'\0' terminated, contain at most one character with strictly pos‐
	    itive width, which must be the first, and contain no characters of
	    negative width.

       The opts argument is reserved for future use.  Currently,  an  applica‐
       tion must provide a null pointer as opts.

       The wcval argument may be a value generated by a call to setcchar or by
       a function that has a cchar_t output argument.  If wcval is constructed
       by any other means, the effect is unspecified.

       When wch is a null pointer, getcchar returns the number of wide charac‐
       ters referenced by wcval.

       When wch is not a null pointer, getcchar	 returns  OK  upon  successful
       completion, and ERR otherwise.

       Upon successful completion, setcchar returns OK.	 Otherwise, it returns

       Functions:      curses(3X),	 wcwidth(3X),	    curs_attr_get(3X),
