Replaces the managed object with the one managed byr orm.

1) Effectively callsreset(r.release()).

2) Effectively callsreset(r.release()).Y* must be implicitly convertible toT*.

3) Effectively callsreset(m.release()).auto_ptr_ref is an implementation-defined type that holds a reference toauto_ptr.std::auto_ptr is implicitlyconvertible to andfrom this type. The implementation is allowed to provide the template with a different name or implement equivalent functionality in other ways.

[edit]Parameters

r	-	another`auto_ptr` to transfer the ownership of the object from
m	-	an object of implementation-defined type that holds a reference to`auto_ptr`

[edit]Return value

*this.

[edit]Notes

The constructor and the copy assignment operator fromauto_ptr_ref is provided to allow copy-constructing and assigningstd::auto_ptr from nameless temporaries. Since its copy constructor and copy assignment operator take the argument as non-const reference, they cannot bind rvalue arguments directly. However, auser-defined conversion can be executed (which releases the originalauto_ptr), followed by a call to the constructor or copy-assignment operator that takeauto_ptr_ref by value. This is an early implementation ofmove semantics.
