curs_getcchar(3X)										    curs_getcchar(3X)

NAME
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 );
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 value wcval - Stores the character attributes in the location pointed to by attrs - 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 using: - 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 positive width, which must be the first, and contain no characters of negative width.
NOTES
The opts argument is reserved for future use. Currently, an application 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.
RETURN VALUES
When wch is a null pointer, getcchar returns the number of wide characters 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.
