* How does FFI work for passing a char* argument that gets modified in the invoked module

char* � ctest ( char* test , char** test2)

{

� � �test = "Modify this argument";

� � �// loop and fill in data into test2 and return..

� � �return "something else";

}

� ctest: test

<cdecl: char* 'ctest' ( char* , long ) module: 'libctest'>

So invoking this with say ExternalAddress allocate: **, �gives us the values as modified by the module.. and be converted as required into ByteArray for the second
