Macro to generate the API struct.

// Shared object: either "libmylibrary.so.1", "mylibrary-1.dll" or "libMyLibrary.dylib"
dl_api::link!(MyApi, "libmylibrary.so.1", {
    fn cFunction(param_name: *mut u32) -> u32;
});

fn main() {
    let api = MyApi::new().unwrap(); // unwrap the `Result`.

    let rtn: u32 = unsafe {
        (api.cFunction)(std::ptr::null_mut())
    };
}
