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 sin-
       gle 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 sin-
       gle-byte and multibyte characters.

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

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

CONFORMING TO
       POSIX.1-2001, POSIX.1-2008, 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.
