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.

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.
