wctob() -- convert wide character to single byte

SYNOPSIS

#include <stdio.h>

#include <wchar.h>

int wctob(wint_t c);

The wctob() function determines whether the specified character 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.

PARAMETERS

c: Is the character to test.

RETURN VALUES

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 the character.
