Re: Undefined values returned by NclReturnValue

Dear NCL team,

I have printed the address of my array in the wrapper function, and in another C code that will be called from NCL:

---> 1: 0x7fb7060e3a30
---> 2: 0x7fb7060e3a50

As you can see, there is a 32 bits shift in the address! What is wrong?

Best,

Li
