## DESCRIPTION

The **wscanf\_l**(), **fwscanf\_l**(), **swscanf\_l**(), **vwscanf\_l**(), **vswscanf\_l**(), and **vfwscanf\_l**() functions are extended locale versions of the **wscanf**(), **fwscanf**(), **swscanf**(), **vwscanf**(), **vswscanf**(), and **vfwscanf**() functions, respectively. Refer to their manual pages for details. Also, see [xlocale(3)](/xlocale/3.md) for more information about extended locales.
