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
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.
