I'd assume that do_CreateInstance() returns the object w/ refcnt=1.
Yes. It returns it as an already_AddRefed<> struct.
The assignment to nsCOMPtr should increase refcount. Correct ?
No, because nsCOMPtr knows not to increase the

You need to run the static analyser.

How could I make it compile error?
I did write
RefPtr xxx = yyy;
xxx.forget();
It is ok for compiling on my Mac.
The comment [1] said " Makes it a compile time error to not use the return
value of a function which has this type", but how do I make the clang
format take effect?
BTW, if you want

You can do this with a return type of

Ok, thanks. Already suspected that (found some similar things in the
code). Could we update the docs (maybe some set of examples) ?
IIRC, there're some places t

Hi folks,
I'm still a bit confused on which types (nsCOMPtr, ...) to use when
exactly, in combination w/ IDLs.
Let's consider a case where an nsArray is created and returned
(as rval, not out-parameter):

[scriptable, uuid(ea0d8b3d-a549-4666-82d8-3a82cee2a3f1)]
