I have this c function

GetR(
OUT ppp ** ppr,
OUT int * pn
)

with this strcuture

typedef struct ppp {
}ppp;

I marshalled like this:

[DllImport("NetApi.dll")]
public static extern int GetR(
[In,Out, MarshalAs(UnmanagedType.LPArray,SizeConst=256)]
IntPtr[]  ppr,
out IntPtr pn
);

in my code i do this:

private IntPtr[] rrr = new IntPtr[10];
public int GetR()
{
int p=GetR(rrr,out j);
if(p==0)
{
for(int iii=0;iii<j.ToInt32();iii++)
{
oo = Marshal.PtrToStructure(rrr[iii],typeof(OB_RESOURCE));
}
}
}
It works fine for the first element, i mean, it only grabs the first
element, i know that there are 6 elements that the method have to
return but only the first is correctly retrieved.

I set breakpoints and inspect the rrr array and only the first element
have data.

Thanks
