SYNOPSIS

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.
