[Boost-users] passing shared_ptr by refereence

Dear All,

is there any reason to prefer (i.e is it safer)
to prefer

some_utility(boost::shared_ptr<Foo> ptr)

to

some_utility(boost::shared_ptr<Foo>& ptr)

or even

some_utility(Foo& ref) (shared ptr is derefed and passed in)

The latter avoiding obviously avoids the increment/decrement
of the ref_count.

thanks

    Sean
