Is it possible to initialize a const char* with a rvalue like string.c_str()?

Question

const char* s = std::string("text").c_str();

std::cout << s << std::endl; //This will print nothing because the data

                             //isn't available any longer

std::string::c_str()

returns a pointer to it's stored data.
In fact that

std::string("text")

is just available for the time i use it (e.g. when I use it initialize an other instance) so in the end the destructor is called which deletes the data which makes s pointing to nothing.

Now my question is if there is a way to move the data somewhere where it's not deleted by the destructor so

const char*

can point to it. Or is it just possible if they would use something like a shared-smart-pointer which knows if something else is pointing to the

std::string

's data so it is not deleted yet.

Copying the data somewhere and pointing to that isn't what I'm looking for.

A string cannot be made to use reference counted pointers internally. If you wish to use a pointer to its data, you must make sure the string survives. The only alternative is copying / moving the data out into another string object.
