NAME
wctob - try to represent a wide character as a single byte
SYNOPSIS
#include <wchar.h>
int wctob(wint_t c);
DESCRIPTION
The wctob() function tests whether the multibyte representation of the wide character c, starting in the initial state, consists of a single byte. If so, it is
returned as an unsigned char.
Never use this function. It cannot help you in writing internationalized programs. Internationalized programs must never distinguish single-byte and multibyte
characters.
RETURN VALUE
The wctob() function returns the single-byte representation of c, if it exists, or EOF otherwise.
ATTRIBUTES

CONFORMING TO
POSIX.1-2001, POSIX.1-2008, C99.
NOTES
The behavior of wctob() depends on the LC_CTYPE category of the current locale.
This function should never be used. Internationalized programs must never distinguish single-byte and multibyte characters. Use either wctomb(3) or the thread-
safe wcrtomb(3) instead.
