Pass array from unmanaged to managed

[songie D]

How can I pass an array from an unmanaged function to a managed one

Say I've go

#pragma unmanage
int GetArray(int* return_array) //return number of member

return_array[0] = 1
return_array[1] = 2
return 2

#pragma manage
...
int thearray __gc[] = new int __gc[2]

...??? Now what??? I can't do GetArray(thearray)
I'm figuring it must be something to do with IntPtr an
probably involves Marshal::Copy at some point, but I can'
see how it's possible to learn how to do this when all the
examples out there are about DLLs that use MarshalA
attribute. How do I do this
