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'' terminated, contain at most one spacing character, which must be the first. Up to CCHARW_MAX-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.
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 con- structed 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. 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.
