wctob(), wctob_l() -- convert wide character to single byte

SYNOPSIS

#include <stdio.h>

#include <wchar.h>

int wctob(wint_t c);

#include <locale.h>

int wctob_l(wint_t c, locale_t locale);

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.

The _l-suffixed version take an explicit locale argument, while the non- suffixed versions use the current global or per-thread locale.

PARAMETERS

c: Is the character to test.
locale: Is a locale_t perhaps returned by newlocale() or LC_GLOBAL_LOCALE or 0 for the current thread locale set with uselocale().

RETURN VALUES

The wctob() and wctob_l() functions 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.

CONFORMANCE

px1_2001;.

MULTITHREAD SAFETY LEVEL
