NAME

wctob - 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 behaviour of this function is affected by the LC_CTYPE category of the current locale.

 RETURN VALUE

The wctob() function returns EOF if c does not correspond to a character with length one in the initial shift state. Otherwise, it returns the single-byte representation of that character.
