Passing non-const references to rvalues in C++

Question

In the following line of code:

bootrec_reset(File(path, size, off), blksize);

Calling a function with prototype:

static void b         


        

Answer 1

Does the upcoming C++0x standard change this in anyway, or is there something the new standard gives me that is more appropriate here, for example all that jibberish about rvalue references?

Yes. Since every name is an lvalue, it is almost trivial to treat any expression as if it was an lvalue:

template <typename T>
T& as_lvalue(T&& x)
{
    return x;
}

// ...

bootrec_reset(as_lvalue(File(path, size, off)), blksize);
