There is no safe way to pass any non-POD type to C code. In your 
example, this means both the shared_ptr object and the pointed-to A object.
You need to ensure the lifetime of the pointer manually, and you need to 
extract the raw pointer and pass that to the C code. You also need to 
make it point to a POD type.
