Fundamentally, your issue is that both Orbix's and omniORB's
interceptors are proprietary interfaces, so you can have no
expectation that they have the same facilities. To port from one to
the other, you are going to have to make some changes to cope with
that.

omniORB has most of the interception points from the portable
interceptors API, so you are generally limited to the facilities of
that.

You can't, since it is fundamentally impossible to know the object
reference the client used. I don't know what the Orbix version does.
Maybe it has a simplistic one-to-one mapping of servants to object
references. You can find the servant if it is activated, by doing a
lookup in the object table. See internal/objectTable.h.

You can't do anything like that.

To do your port, you're going to have to step back a stage, and think
how to implement the requirements you have using the tools that
omniORB provides. You can't do a simple like-for-like port from the
Orbix code.

Cheers,

Duncan.
