Bus/DEv/Func Numbers

Question

Hello Folks -
Is there an easy way to get the Bus/Dev/Func Numbers from a Solaris PCI driver? I've been looking all afternoon, and have come up with ddi_prop_lookup_byte_array() with the "reg" property. If the way to do such a thing, I am not sure how to properly parse the value returned (all 80 bytes).
Any other ideas here?
Thanks,
mike

OK, I think I have found a way for a PCI device driver to get the Bus/Dev/Func Numbers of the device it is trying to control. This was all from trial and error. I'd appreciate comments from any people who have been there/done that.
   int       val;
   int       *props;
   unsigned int   numProps;
   val = ddi_prop_lookup_int_array(
            DDI_DEV_T_ANY,
            devi,
            0,
            "reg",
            &props,
            &numProps);
   if((val == DDI_PROP_SUCCESS) && (numProps > 0))
      p_mps->busNum  = PCI_REG_BUS_G(props[0]);
      p_mps->devNum  = PCI_REG_DEV_G(props[0]);
      p_mps->funcNum = PCI_REG_FUNC_G(props[0]);
      ddi_prop_free(props);
