Re: Interoperability with Visibroker arrays inside structs passing

[Sergiu Gavrila <sg itdesign de>]

Title:

Thanks for the fast response, I did enabled the debug and start digging into
ORBit2 sources. The problem seams to be with the ORBit_marshal_value function
from corba_any.c. For the TypeCode CORBA_tk_array I have removed the switch
and let only the default brach and now it looks like the problem is solved.
I still have to do some better tests (next week) .

So the part:
-----------------
case CORBA_tk_array:
        switch (tc->subtypes[0]->kind) {
        case CORBA_tk_boolean:
        case CORBA_tk_char:
        case CORBA_tk_octet:
            giop_send_buffer_append (buf, val, tc->length);
            break;
        default: {
            int align = tc->subtypes[0]->c_align;
            
              for (i = 0; i < tc->length; i++) {
                ORBit_marshal_value (buf, val, tc->subtypes[0]);
                
                *val = ALIGN_ADDRESS (*val, align);
            }
            break;
        }
        }
        break;
--------------
became:
---------------
case CORBA_tk_array:
     for (i = 0; i < tc->length; i++) {
                ORBit_marshal_value (buf, val, tc->subtypes[0]);      
        
                *val = ALIGN_ADDRESS (*val, tc->subtypes[0]->c_align);
    }


Mark, do you have some time to take a look and tell me if this modification
is ok?
