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.
