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'
