NAME

6       wctob - wide-character to single-byte conversion
7

SYNOPSIS

9       #include <stdio.h>
10       #include <wchar.h>
11
12       int wctob(wint_t c);
13
14

DESCRIPTION

16       The  wctob() function shall determine whether c corresponds to a member
17       of the extended character set whose character representation is a  sin‐
18       gle byte when in the initial shift state.
19
20       The  behavior  of this function shall be affected by the LC_CTYPE cate‐
21       gory of the current locale.
22

RETURN VALUE

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