 | Option | Description |

-| **_ENABLE_PER_THREAD_LOCALE** | Make the current thread use a thread-specific locale. Subsequent calls to **setlocale** in this thread affect only the thread's own locale. |
-| **_DISABLE_PER_THREAD_LOCALE** | Make the current thread use the global locale. Subsequent calls to **setlocale** in this thread affect other threads using the global locale. |

 | **0** | Retrieves the current setting for this particular thread. |
 
-These functions affect the behavior of **setlocale**, **_tsetlocale**, **_wsetlocale**, and **_setmbcp**. When per-thread locale is disabled, any subsequent call to **setlocale** or **_wsetlocale** changes the locale of all threads that use the global locale. When per-thread locale is enabled, **setlocale** or **_wsetlocale** only affects the current thread's locale.

-If *per_thread_locale_type* is not one of the values listed in the table, this function invokes the invalid parameter handler, as described in [Parameter Validation](../../c-runtime-library/parameter-validation.md). If execution is allowed to continue, this function sets **errno** to **EINVAL** and returns -1.
