RE: Problems marshalling an any

["Verwerft, Marc" <MVerwerft nedcar nl>]

Hi Sebastian,

No, I'm not using the ORBit event server. I noticed in the documentation
that it wasn't ready.
I am using the JavaORB event service to attach to as an (ORBit) client.

The problems I'm having now are related to sending an 'any' value across.
I'm currently using the test-any-client/server to track down what's going on
and found what's happening.

Snippet from ORBit_marshal_value() in corba_any.c :
         case CORBA_tk_string :
	ulval = strlen(*(char **)*val) + 1;
	
	*val = ALIGN_ADDRESS(*val, ALIGNOF_CORBA_POINTER);

	giop_send_buffer_append_mem_indirect_a(buf,
					       &ulval,
					       sizeof(CORBA_unsigned_long));
	giop_message_buffer_append_mem(GIOP_MESSAGE_BUFFER(buf), *(char
**)*val, ulval);
	
For marshalling the data, the ALIGN_ADDRESS(addr,boundary) macro is used.
However in the config.h file I have a #define ALIGNOF_CORBA_POINTER 0 (All
other ALIGNOF_ defines are also 0). Using this I invariably get as result 0
and the program crashes when invoking giop_message_buffer_append_mem().

So, I should probably alter these definitions. Since I cannot run the
configure script on OpenVMS, could you mail me your settings (and probably
CPU type) to use as a starting point ?

Thanks for helping me out.

Marc.

I've got an enormous mind. Sometimes it takes me a whole week to make it up.
