c atoi() for wide chars on linux?

Is there a c atoi() equivalent for wide chars on Linu开发者_C百科x? I can find something for MS (wtoi) but I can find anything in a standard Linux lib.

You can use wcstol to convert from wide strings to integer values.

It is unusual for a Linux program to use wchar_t type.

The reason being that Linux uses utf-8 as the standard encoding. char const* strings are assumed to be utf-8 strings by glibc. Ascii digits and utf-8 digits have the same byte representation, so that atoi() works both on ascii and utf-8 strings.

Having said that, look in #include <wchar.t>, it provides wcstol().
