wctob(3) - Linux man page

Name

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

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, of EOF otherwise.

Conforming to

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.
