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.
