How to read back the PXIe bus routing and reserving status programmatically through NI-VISA API?

[YTHung]

Hi,

I have a PXIe-1085 18-slot chassis. I'm trying to routing and reserving triggers through NI-VISA API just like the particular functionality of NI-MAX (refer to the picture below).

Are there any APIs I can use to getting the bus status after I set reservation and routing through NI-VISA API?

I found that viGetAttrbute( ) can get the value I just set,  but it can't indicates the rounting status of bus.

thanks,
