DUPLOCALE(3)						   BSD Library Functions Manual 					      DUPLOCALE(3)

NAME

     duplocale -- duplicate an locale

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <xlocale.h>

     locale_t
     duplocale(locale_t locale);

DESCRIPTION

     Duplicates an existing locale_t returning a new locale_t that refers to the same locale values but has an independent internal state.  Vari-
     ous functions, such as mblen(3) require a persistent state.  These functions formerly used static variables and calls to them from multiple
     threads had undefined behavior.  They now use fields in the locale_t associated with the current thread by uselocale(3).  These calls are
     therefore only thread safe on threads with a unique per-thread locale.  The locale returned by this call must be freed with freelocale(3).

SEE ALSO

     freelocale(3), localeconv(3), newlocale(3), querylocale(3), uselocale(3), xlocale(3)

STANDARDS

     This function conforms to IEEE Std 1003.1-2008 (``POSIX.1'').

BUGS

     Ideally, uselocale(3) should make a copy of the locale_t implicitly to ensure thread safety, and a copy of the global locale should be
     installed lazily on each thread.  The FreeBSD implementation does not do this, for compatibility with Darwin.

NEWLOCALE(3)						   BSD Library Functions Manual 					      NEWLOCALE(3)

NAME

     newlocale -- Create a new locale

SYNOPSIS

     #include <xlocale.h>

     locale_t
     newlocale(int mask, const char * locale, locale_t base);

DESCRIPTION

     Creates a new locale_t based off the locale specified by base.  The categories specified by mask will be replaced to correspond with the
     named locale.

     The mask is the logical OR of the following:

     LC_COLLATE_MASK   Collation

     LC_CTYPE_MASK     Character type

     LC_MESSAGES_MASK  Messages

     LC_MONETARY_MASK  Monetary

     LC_NUMERIC_MASK   Numeric

     LC_TIME_MASK      Time

     LC_ALL_MASK       The logical OR of all of the above

     The locale string is typically the name of one of the directories in /usr/share/locale.  If locale is NULL, then the C locale is used. If
     locale is an empty string, then it will look for environment variables: LC_ALL, then LC_* if the corresponding LC_*_MASK bit is set, then the
     LANG environment variable. If none of these are found, it will default to the C locale.

     If base is NULL, the current locale is used. If base is LC_GLOBAL_LOCALE, the global locale is used.

     If mask is LC_ALL_MASK, base is ignored. In order to create a C locale_t value, use newlocale(LC_ALL_MASK, NULL, NULL).

RETURN VALUES

     Returns a new locale_t, or NULL in case of error.	New locales should be freed with freelocale(3).
