WCTOB(3)                   Linux Programmer's Manual                  WCTOB(3)

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 wc-
       tomb(3) or the thread-safe wcrtomb(3) instead.
