WCTOB 3C "Jun 25, 2014"
NAME
wctob, wctob_l - wide-character to single-byte conversion
SYNOPSIS

#include <stdio.h>
#include <wchar.h>

int wctob(wint_t c);

#include <stdio.h>
#include <wchar.h>
#include <xlocale.h>

int wctob_l(wint_t c, locale_t loc);
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 wctob() is affected by the LC_CTYPE category of the current locale. See environ(5)

The function wctob_l() behaves identically to wctob(), except instead of operating in the current locale, it operates in the locale specified by loc.

RETURN VALUES

These functions return EOF if c does not correspond to a character with length one in the initial shift state. Otherwise, they return the single-byte representation of that character.

ERRORS

No errors are defined.

ATTRIBUTES

See attributes(5) for descriptions of the following attributes:

Interface Stability See below

The wctob() function is Standard. The wctob_l() function is Uncommitted.
