Trying to get value from unmanaged memory

Hello everyone.

I'm working on my Unity project with teamspeak and I have to retrieve some id. I have to transfert my id from a unmanaged memory to managed one (with Marshalling) .

So I have this snipset of code :

anyID **list = NULL; list = (anyID**)malloc(sizeof(anyID));

         error = Ts3client.ts3client_getClientList(scHandlerID,ref list);
         if(error != public_errors.ERROR_ok)
             Debug.Log("error client list");

         string test = Marshal.PtrToStringAnsi(list);

with :

unsigned intts3client_getClientList(serverConnectionHandlerID, result);
uint64 serverConnectionHandlerID;
anyID** result;

I have compiler error that's saying : Pointers and fixed size buffers may only be used in an unsafe context

Do you have an idea how can I fix this ? Thanks a lot guys
