40140 - need getter_InOut for XPIDL inout string params

Status: RESOLVED DUPLICATE of bug 53065

(Core :: XPCOM, enhancement, P3)

Description

[Mike Shaver (:shaver -- probably not reading bugmail closely)]

So that we can do:
nsXPIDLString foo = getter_Copies(strdup("foo"));
obj->InOutMethod(getter_InOut(foo));

It should assert (ideally not compile, maybe we can do that with New Strings) if
I try:

nsXPIDLString foo = getter_Shares("foo");
obj->InOutMethod(getter_InOut(foo));

Hmmm...

Comment 2

I'm folding XPIDL strings into the main stream string classes, this will cease
to be an issue at that time, at which point, I'll mark this bug FIXED.

|nsXPIDL[C]String| is really like an |auto_ptr| for strings.  We're going to
merge that functionality into the shared buffer implementation described in bug
#53065.  Eventually, that implementation will replace |ns[C]String| for all
clients in mozilla.

Comment 4

[Scott Collins]

bug #53065 already requires that the new default string, |nsCommon[C]String|,
implment |nsXPIDL[C]String| functionality, including being re-bindable (the
primary characteristic of an in/out parameter).  That was how this functionality
was to be merged.  Therefore, this bug is now a dup.
