shared_ptr<FILE> foo(fread("foo.txt","r"),fclose);
Why not something like the following: shared_ptr<FILE> foo(fopen("foo.txt","r"), call_if_arg_not_null(fclose)); With call_if_arg_not_null being a functor (based on boost::function or whatever) that simply calls fclose only if the argument is nonzero. I think the obvious rationale is that while both approaches have their merits, you can indeed implement the one based on the other but not vice versa.
