std::auto_ptr<T>::operator=

Replaces the managed object with the one managed by r or m.

# Declarations

auto_ptr& operator=( auto_ptr& r ) throw();

(deprecated in C++11) (removed in C++17)

template< class Y >
auto_ptr& operator=( auto_ptr<Y>& r ) throw();

(deprecated in C++11) (removed in C++17)

auto_ptr& operator=( auto_ptr_ref<T> m ) throw();

(deprecated in C++11) (removed in C++17)

# 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

# Return value

*this.

# Notes

The constructor and the copy assignment operator from auto_ptr_ref is provided to allow copy-constructing and assigning std::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, a user-defined conversion can be executed (which releases the original auto_ptr), followed by a call to the constructor or copy-assignment operator that take auto_ptr_ref by value. This is an early implementation of move semantics.
