NAME

       wctob - try to represent a wide character as a single byte

LIBRARY

       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 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  internationalized  programs.   Internationalized
       programs must never distinguish single-byte and multibyte characters.

RETURN VALUE

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

HISTORY

       POSIX.1-2001, 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.
