## SYNOPSIS

**#include \<stdio.h\>**

**#include \<xlocale.h\>**

*int*\

**fscanf\_l**(*FILE \* restrict stream*, *locale\_t loc*, *const char \* restrict format*, *...*);

*int*\

**scanf\_l**(*locale\_t loc*, *const char \* restrict format*, *...*);

*int*\

**sscanf\_l**(*const char \* restrict str*, *locale\_t loc*, *const char \* restrict format*, *...*);

**#include \<stdarg.h\>**

**#include \<xlocale.h\>**

*int*\

**vfscanf\_l**(*FILE \* restrict stream*, *locale\_t loc*, *const char \* restrict format*, *va\_list ap*);

*int*\

**vscanf\_l**(*locale\_t loc*, *const char \* restrict format*, *va\_list ap*);

*int*\

**vsscanf\_l**(*const char \* restrict str*, *locale\_t loc*, *const char \* restrict format*, *va\_list ap*);

## DESCRIPTION

The **scanf\_l**(), **fscanf\_l**(), **sscanf\_l**(), **vscanf\_l**(), **vsscanf\_l**(), and **vfscanf\_l**() functions are extended locale versions of the **scanf**(), **fscanf**(), **sscanf**(), **vscanf**(), **vsscanf**(), and **vfscanf**() functions, respectively. Refer to their manual pages for details. Also, see [xlocale(3)](/xlocale/3.md) for more information about extended locales.
