duplocale()

duplicate a locale 

Function

SYNOPSIS

#include <locale.h>

locale_t duplocale(locale_t locale);

DESCRIPTION

Duplicates an existing locale returning a new locale_t that refers to the same locale values but has an independent internal state. Various functions, such as mblen() 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(). 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().

Standards Conformance

The function conforms to IEEE Std 1003.1-2008 'POSIX.1'
