[omniORB] Regarding Datatype in C++

[Rajesh Khan]

Hi is there anyway to quickly familiarize with the datatypes being used .
It gets confusing sometimes for example
CORBA::ORB_var orb = CORBA::ORB_init(argc, argv);
CORBA::Object_var obj = getObjectReference(orb); //orb is of type
CORBA::ORB_var

However its being passed to a function which requires CORBA::ORB_ptr
static CORBA::Object_ptr getObjectReference(CORBA::ORB_ptr orb)
{...... }

Hi is there anyway to quickly familiarize with the datatypes being used . It
gets confusing sometimes for example
??? ??? CORBA::ORB_var orb = CORBA::ORB_init(argc, argv);
??? ??? CORBA::Object_var obj = getObjectReference(orb);? //orb is of type
CORBA::ORB_var
However its being passed to a function which requires CORBA::ORB_ptr
static CORBA::Object_ptr getObjectReference(CORBA::ORB_ptr orb)

That's the correct way to do it.

The IDL to C++ mapping is very difficult and can't really be explained
over a mailing list. You can download a copy of the mapping from the
OMG website. You should also get the book: Advanced CORBA Programming
with C++ by Henning & Vinoski. That book is really not optional if you
are going to try to learn CORBA in C++.
