WCTOB(3C)WCTOB(3C)NAMEwctob - wide-character to single-byte conversion
SYNOPSIS
#include <stdio.h>
#include <wchar.h>
int wctob(wint_t c);
DESCRIPTION
The wctob() function determines 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 is affected by the LC_CTYPE category of
the current locale. See environ(5)RETURN VALUES
The wctob() function returns EOF if c does not correspond to a charac‐
ter with length one in the initial shift state. Otherwise, it returns
the single-byte representation of that character.
ERRORS
No errors are defined.
