NAME

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

LIBRARY

Standard C library (libc,~-lc)

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 singl-byte and multibyte characters.

RETURN VALUE

The wctob() function returns the singl-byte representation of c, if it exists, or EOF otherwise.

ATTRIBUTES

For an explanation of the terms used in this section, see attributes(7).

Interface	Attribute	Value

STANDARDS

C11, POSIX.-2008.

HISTORY

POSIX.-2001, 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 singl-byte and multibyte characters. Use either wctomb(3) or the threa-safe wcrtomb(3) instead.
