complicated P/Invoke and marshaling

[c_xyTopa]

hi all!
i have a c++ function, wich has to be invoked from c#.
c++ function looks like that:

uint Function(const Request* a, uint max, Result** b, const Result *c,
uint* d, void *cb)

typedef struct{
uint a,
wchar_t b,
Position p,
Position* p,
uint *c
}Request;

typedef struct{
uint a,
uint b
}Position;


1. how do i declare that function?
2. how do i declare the structs?
3. the other question is how i use the declared function?
i need to declare struct Request and pass a reference to a struct as
first parameter. the third parameter expects a reference to the pointer
to the struct. How can i solve that?

thanx in advance

Which version of the CF are you targeting?

 

[c_xyTopa]

cgautil says CF [1.0.3316.00]
if i target a new CF 2.0, what hapens then?

i've read their are limits of parameter pasing.
one of them is passing structcs that contain structs or unions.

are those limitations not effective in CF 2.0?
