NIDMM and VTEXDMM in simulation creating different results / errors - why?

Hello,

i installed NIDMM-driver and VTEXDMM-driver and configured them to simulate with specific driver.

I am then calling only the iviDmm generic functions in C++.

In the list below i copied all results of the functions.

Column one is NIDMM and colum two VTEXDMM.

Now i wonder why:

1) "Read" is working at NIDMM and not at VTEXDMM (but Init/Fetch is working on both sides)

2) Some Configure-Functions are not working at NIDMM but on VTEXDMM

3a) Read/Fetch Multipoint are not working on both sides...

3b) ...but NIDMM still returns 10 actualPts

How can this be explained?

Is the execution order not correct?

Thanks for help
