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 international-
       ized 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.
