wctob

(3)

try to represent a wide character as a single byte

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

LIBRARY

Standard C library (libc, -lc)

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

STANDARDS

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.
