[Mono-list] Mono embedding: invoke c code with char*

[Ing. Francesco Carsana]

Hi,

I'm working with mono embedding, and I'm trying
to invoke a c function that accepts two
parameters:

    [MethodImpl(MethodImplOptions.InternalCall)]
    private unsafe extern static void
      OnConnectHandler(char* _ipAddress, bool _connected);

This function is invoked inside this method:

    private static void OnConnect(string _ip, bool _conn);

The problem is: how can I convert string to char*?
Is it possible to invoke mono_string_to_utf8?

Thank You.

Francesco.
