Calling unmanged DLL function with complex struct as parameters

[NewsBot]

What would be the porper way to call

MyFunc(int, int, Struct2*) which is in unmanaged DLL from C# code?

 

Where

Struct2

{

int

int

Struct1[sOME_CONST]

}

 

or

{

int

int

Struct1*

}

 

I've tried to define STRUCT2 in managed code as

[StructLayout(LayoutKind.Sequential)]

publicstructSTRUCT2

{

publicint XINT;

publicint YINT;

[MarshalAs(UnmanagedType.LPStruct, SizeConst = SOME_CONST)]

publicSTRUCT1[]someStruct;

}

 

and then calling

 

STRUCT2 myStruct2;*

MyFunc(someInt, someOtherInt, myStruct2);

 

 

but looks like LPStruct is reserved for some misterious use (MSDN articles/help didn't help much).

 

Any ideas?
