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 characterc
, 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 ofc
, if it exists, or EOF otherwise. Attributes

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.
