How to use smart pointers with a function which takes raw pointer

This depends on the smart pointer type you are using. Are you talking
about boost::shared_ptr? If so, look for get() in the official
documentation:

How to use smart pointers with a function which takes raw pointer

Do you mean something like

void foo(char* arg1)
{
auto_ptr<char>(arg1)
//Do something
}

How to use smart pointers with a function which takes raw pointer

Just pass the raw pointer to the function (e.g. use get () or whatever
memeber function your particular smart pointer has to retrieve the raw
pointer it holds)

A well designed stand alone function should not delete the pointer (it
didn't allocated the object did it?) and since the object exists
before the function was called (and will after the function is called)
there is no need to manage it's memory.

That depends on what the function is supposed to do. If the
function's role involves deleting the object, it should delete
it. Otherwise, you'll end up with a lot of memory leaks.

You are correct. But I used the term "well designed". It strikes me
as not a very good design to have smart pointers (in presumably new
code)
call a function (presumably in old/legacy code) that deletes an
object.
I assumed the OP had or was at least striving for good design.
