"Correct" way to return empty shared_ptr?

What is the 'correct' way to return a NULL/empty shared_ptr?  For example,
this works

<snippet>
shared_ptr<int> maybe_get_a_pointer()
{
      shared_ptr<int> p;
      return(p);
}
</snippet>

but seems 'klunky'.  I've clearly missed something in the docs/examples
somewhere.  Can someone point me in the right direction?

TIA
