WCTOB(P) POSIX Programmer's Manual WCTOB(P)NAMEwctob - 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 sin‐
gle byte when in the initial shift state.
The behavior of this function shall be affected by the LC_CTYPE cate‐
gory 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.
