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

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

*intmax\_t*\

**wcstoimax\_l**(*const wchar\_t \* restrict nptr*, *wchar\_t \*\* restrict endptr*, *int base*, *locale\_t loc*);

## DESCRIPTION

The **wcstol\_l**(), **wcstoul\_l**(), **wcstoll\_l**(), **wcstoull\_l**(), **wcstoimax\_l**() and **wcstoumax\_l**() functions are extended locale versions of the **wcstol**(), **wcstoul**(), **wcstoll**(), **wcstoull**(), **wcstoimax**() and **wcstoumax**() functions, respectively. Refer to their manual pages for details. Also, see [xlocale(3)](/xlocale/3.md) for more information about extended locales.
