Returns the locale identifier of the current locale for the calling thread.
Note This function can retrieve data that changes between releases, for example, due to a custom locale. If your application must persist or transmit data, see Using Persistent Locale Data.
Syntax
LCID GetThreadLocale();
Return value
Returns the locale identifier of the locale associated with the current thread.
Windows Vista: This function can return the identifier of a custom locale. If the current thread locale is a custom locale, the function returns LOCALE_CUSTOM_DEFAULT. If the current thread locale is a supplemental custom locale, the function can return LOCALE_CUSTOM_UNSPECIFIED. All supplemental locales share this locale identifier.
Remarks
When an application process launches, it uses the Standards and Formats variable for the locale. For more information, see NLS Terminology.
When a new thread is created in a process, it inherits the locale of the creating thread. This locale can be either the default Standards and Formats locale or a different locale set for the creating thread in a call to SetThreadLocale. GetThreadLocale and SetThreadLocale can be used to modify the locale of the new thread.
