The BonoboStorage C interface is extremely simple, this is since the CORBA client interface is where the action occurs. It is anticipated that relatively few people need to implement the Bonobo/Storage IDL interface.
The common entry point for BonoboStorage is that of opening a storage using the bonobo_storage_open function, perhaps by a container to use to persist a compound document:
Example 1. An example storage use case
void
container_save (SampleApp *app,
const char *filename,
CORBA_Environment *ev)
{
BonoboStorage *storage;
Bonobo_Storage corba_storage;
GList *components;
int i;
storage = bonobo_storage_open (STORAGE_TYPE, filename,
Bonobo_Storage_READ |
Bonobo_Storage_WRITE |
Bonobo_Storage_CREATE,
0664);
g_return_if_fail (storage);
corba_storage = BONOBO_OBJREF (storage);
...
Serialize components to streams created in the storage
...
Bonobo_Storage_commit (corba_storage, ev);
CORBA_exception_free (ev);
bonobo_object_unref (BONOBO_OBJECT (storage));
}
