Uhm - not 100% sure about that. (i32*) means - one i32 parameter, 
followed by a varargs list - e.g. in C

f(int i, ...)

So, how can you prove that an Array[Int] is the right type to hold all 
of the parameters?

One thing you might want to consider actually, would be for you to use 
the SystemABI API directly, to get a MethodHandle that accessed the 
right native function, and maybe add a varargs adaptation on top. In 
other words, I'm not sure how much of what you are doing needs 
panama/foreign an the annotation stuff, and how much of what you could 
do using the low level support in foreign-abi. Since that's lower level 
it will give you many more options on how to surface it at the Scala level.
