## DESCRIPTION

The **wprintf\_l**(), **fwprintf\_l**(), **swprintf\_l**(), **vwprintf\_l**(), **vfwprintf\_l**(), and **vswprintf\_l**() functions are extended locale versions of the **wprintf**(), **fwprintf**(), **swprintf**(), **vwprintf**(), **vfwprintf**(), and **vswprintf**() functions, respectively. Refer to their manual pages for details. Also, see [xlocale(3)](/xlocale/3.md) for more information about extended locales.
