NAMEwctob − try to represent a wide character as a single byte

---

LIBRARYStandard C library (libc, −lc)

---

SYNOPSIS#include <wchar.h>int wctob(wint_t c);

---

DESCRIPTIONThe 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 VALUEThe wctob() function returns the single-byte representation of c, if it exists, or EOF otherwise.

---

ATTRIBUTESFor an explanation of the terms used in this section, see attributes(7). InterfaceAttributeValue wctob() Thread safetyMT-Safe

---

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

---

NOTESThe 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.
