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 single-byte and multibyte characters.

RETURN VALUE

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

ATTRIBUTES

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

STANDARDS

C11, POSIX.1-2008.

HISTORY

POSIX.1-2001, 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 single-byte and multibyte characters. Use either wctomb (3) or the thread-safe wcrtomb (3) instead.
