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

How can I force GCC to permit this code?

If you own the definition of File then you can try playing tricks such as this one:

class File /* ... */ {
public:
  File* operator&() { return this; }
/* ... */
};
/* ... */
bootrec_reset(*&File(path, size, off), blksize);

This compiles for me in c++98 mode.

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?

Obviously this the way to go if at all possible.
