Convert a wide-character code into a UTF-8 character

Synopsis:

int wctoutf8( char *s,
              wchar_t wc );

Arguments:

s

A pointer to a location where wctoutf8() stores the UTF-8 character corresponding to wc.

wc

The wide character to be converted.

Library:

Description:

The wctoutf8() function stores the multibyte representation corresponding to the code contained in wc in the array pointed to by s. This function stores at most MB_CUR_MAX characters.

The wctoutf8() function is similar to wctomb(), except:

• wctoutf8() isn't affected by the current locale.
• The s argument isn't allowed to be NULL.

Returns:

-1

The value of wc doesn't correspond to a valid multibyte character.

> 0

The number of bytes that comprise the multibyte character corresponding to the value of wc.
