wctob - try to represent a wide character as a single byte

  #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).

POSIX.1-2001, POSIX.1-2008, C99.

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.

*btowc*(3), *wcrtomb*(3), *wctomb*(3)
