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.

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.
