Hi, I have a shared pointer like this class a { }; boost::shared_ptr<a> Ptr(new a()); I need to pass this pointer as an argument to function (MyFunc) which access this as a reference void MyFunc(a& ref) { } Now I am calling the function like this MyFunc(*Ptr); But this causes the "Ptr" to destroy early (I am using this for an asynchronous-ASIO- operation) How can I do this right?

Ptr is destroyed when it goes out of scope. If there no more shared_ptr's to this object - it gets deleted as well. It's not a good idea to store references or raw pointers to an object, which is managed by shared_ptr.
