I'd advise against using T_ARRAY, RARRAY_PTR etc, writing stuff with  
the following methods makes life a lot easier for other Ruby  
implementations that also support MRI C extensions:

rb_ary_new(void);
rb_ary_push(VALUE array, VALUE element);
rb_ary_entry(VALUE array, long i);
rb_ary_store(VALUE array, long i, VALUE element);
