I am not clear about how the CLR will act if we pass a reference OR pointer
to a unmanaged code via Pinvoke. ( Both are treated alike with the only diff
being we need to encapsulate the code using '&' with UNSAFE and pin the
location ????? )
I read the useful article by Jon Pryor (
It states the 4 steps for marshaling...what happens if you pass a
NON_BLITTABLE STRUCTURE by reference (without pinning it) or pass a pointer
to this structure.
Will this be
Content of pointer copied to UM memory---- > marshaling done --- > (
Unmanaged code makes operates on it / changes ) ---> result marshaled BACK
to managed types ---> result copied to managed memory
And do the above steps take place for "class pass by reference" ???
Awaiting some reply from the experts out there !!
