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

 

getcchar

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
 

setcchar

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 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 constructed by any other means, the effect is unspecified.  

RETURN VALUE

When wch is a null pointer, getcchar returns the number of wide characters referenced by wcval, including one for a trailing null.

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.
