wctob(3) Library Functions Manual wctob(3)
wctob - try to represent a wide character as a single byte
Standard C library (libc, -lc)
#include <wchar.h>
int wctob(wint_t c);
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.
The wctob() function returns the single-byte representation of c,
if it exists, or EOF otherwise.
For an explanation of the terms used in this section, see
attributes(7).

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.
