PROLOG
       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME
       wctob - wide-character to single-byte conversion

SYNOPSIS
       #include <stdio.h>
       #include <wchar.h>

       int wctob(wint_t c);

DESCRIPTION
       The wctob() function shall determine whether c corresponds to a member of the extended character set whose character  representation  is  a
       single byte when in the initial shift state.

       The behavior of this function shall be affected by the LC_CTYPE category of the current locale.

RETURN VALUE
       The  wctob()  function  shall  return EOF if c does not correspond to a character with length one in the initial shift state. Otherwise, it
       shall return the single-byte representation of that character as an unsigned char converted to int.

ERRORS
       No errors are defined.
