The struct used to store the types (rb_data_type_t) contains a "data" field where we can store whatever we want. I use that field to store a pointer to the corresponding destroy function. For example notmuch_rb_database_type contains a pointer to notmuch_database_destroy. I cast that pointer as a notmuch_status_t (func*)(void *) and call that function passing the internal object (e.g. notmuch_database_t). Using the rb_data_type_t data we can call the correct notmuch destroy function. Therefore this: ret = ((notmuch_status_t (*)(void *)) type->data) (nm_object); Is effectively the same as this: ret = notmuch_database_destroy (database); The advantage of doing it this way is that much less code is necesary since each rb_data_type_t has the corresponding destroy function stored in it.
