I think this needs a quick update, it should be unsigned int amount, instead of double amount, if I am right, I can write that little "fix"

@juanarbol The current code is correct – we want the returned value to be a JS number, which corresponds to double in C++. The assignment to double amount = ... does the conversion implicitly, which is fine for us (although you could add static_cast<double>(...) to make it more explicit).

If we did use unsigned int amount, the amount value would be truncated to the size of an unsigned int, which is typically 32 bits; but the value returned from libuv won’t usually fit into that range, so we’d actually get a wrong result in that case.
