# Error code E0044

You cannot use type or const parameters on foreign items.

Example of erroneous code:

    #![allow(unused)]
    fn main() {
    extern "C" { fn some_func<T>(x: T); }
    }

To fix this, replace the generic parameter with the specializations that you need:

    #![allow(unused)]
    fn main() {
    extern "C" { fn some_func_i32(x: i32); }
    extern "C" { fn some_func_i64(x: i64); }
    }
