[Mono-dev] add_internal_call with int32[]

[Jonathan Mitchell]

Try

mono_add_internal_call("testObj::mono_testObj_fromInts(object,int[])", mono_testObj_fromInts);

It’s very handy to have some utility code to iterate over a managed class and dump out the native method signatures.
It can save a lot of time when you have complex signatures.
