DLLExport Example with by-ref parameters

[Markus1980Wien]

Can you please provide an example where a complex type or an arrary of complex types is handed to c# by ref.

Unmanaged code (c++) creates a complex type and fills this type with some data.
Unmanaged code calls an c# Function and hands over the complex type.
c# Reads the data that has been provided by unmanaged code.
c# Modifies the data and hands back the modified data to unmanaged code.
Unmanaged code (c++) uses the data which has been modified by c#.
