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).
