What is the release method supposed to do when the use-count > 1 ?

Seems reasonable to me. (I have to code in a C/C++ environment where
returning a C pointer is required by the called API.)

Would a better example be:
  void foo(std::list<data *> &myList, int x)
  {
       shared_ptr<data> theData(new data(x) );
       myList.push_back(theData.get() );
       theData.release();
  }

(I know it could be improved by having a list of shared_ptrs, but sometimes
that change isn't possible due to who controls the code.  Third party
software etc. )
