to instance objects...

[Matteo Airaghi <teoair tin it>]

Hello,
I have a problem...
I realized 3 interfaces in my system and now I want to use methods of an
intereface inside the implementation of another interface.
To do this I need to invoke the CosNaming service and, given the
identifier string to the service, get the handle to the object to use
it.
The CosNaming invocation begins with the CORBA_orb_init() and
CORBA_orb_resolve_initial_references(). This allows me to have the orb
(CORBA_orb type) and the name server (CosNaming_NamingContext type).
For all these things I need the IOR output; so I thought to write this
IOR in a file, read the file to access it and use it in the
CORBA_orb_init().
This procedure seems very complex and I believe it exists another one,
easier. Is it??
Moreover this procedure, as I implemented it, doesn't work (I receive an
error message of segmentation fault). So I'm looking for a new way or a
tip that correct my code.
PLEASE HELP ME!
I hope I sufficiently well explained my question... I attach a code
fragment to clarify...

Thanks a lot
Matteo
