curs_getcchar(3)					      curs_getcchar(3)

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

SYNOPSIS
       #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 );

LIBRARY
       Curses Library (libcurses)

STANDARDS
       Interfaces documented on this reference page conform to industry	 stan‐
       dards as follows:

       getcchar, setcchar:  XCURSES4.2

       Refer  to  the  standards(5)  reference page for more information about
       industry standards and associated tags.

DESCRIPTION
       The getcchar function gets a wide-character string and rendition from a
       cchar_t argument. When wch is not a null pointer, the getcchar function
       does the following: Extracts information from a	cchar_t	 type  defined
       for  wcval  Stores the character attributes in the object pointed to by
       attrs Stores the color-pair in the  object  pointed  to	by  color_pair
       Stores  the  wide-character string, both spacing and nonspacing charac‐
       ters 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, both spacing and non-spacing
       characters, in the object pointed to  by	 wcval	Does  not  change  the
       objects pointed to by attrs or color_pair

       The  setcchar  function	initializes  the object pointed to by wcval by
       using: The character attributes in attrs The color pair	in  color_pair
       The wide-character string pointed to by wch

       The  wch	 value	should contain either a spacing character, followed by
       nonspacing characters, or just the nonspacing characters.

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

NOTES
       The  header  file  <curses.h>  automatically  includes  the header file
       <stdio.h>.

       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.

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

       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
       ERR.
