Re: [Boost-users] shared_ptr as reference argument

Is there some utility in passing shared_ptr's as references as here:

void bla(boost::shared_ptr<T>& bla_ptr);

This avoids creating of a new object and copying overhead, but is it safe? When would you recommend it and when not?

Why wouldn't it be safe? Unless the function stores a pointer or reference to the shared_ptr after it returns, there is no danger. In Christ, Steven Watanabe
