C# - Calling Novell API function (solution)

Here's a quick C# sample on how to call a Novell API function (solution).

public class IcNovell
{
[DllImport("calwin32.dll")] public static extern int NWCallsInit(byte reserved1, byte reserved2);
[DllImport("netwin32.dll", EntryPoint = "NWDSCreateContextHandle")] public static extern int NWDSCreateContextHandle(ref int context);
[DllImport("netwin32.dll", EntryPoint = "NWDSWhoAmI")] public static extern int NWDSWhoAmI(int context, StringBuilder NovellUserId);
[DllImport("netwin32.dll", EntryPoint = "NWDSFreeContext")] public static extern int NWDSFreeContext(int context);
}

private void button1_Click(object sender, EventArgs e)
{
int cCode = IcNovell.NWCallsInit(0, 0);
if (cCode == 0)
{
    int NovellContext = 0;
    cCode = IcNovell.NWDSCreateContextHandle(ref NovellContext);
    if (cCode == 0)
    {
      StringBuilder NovellUserId = new StringBuilder(256);
      cCode = IcNovell.NWDSWhoAmI(NovellContext, NovellUserId);
      if (cCode == 0)
      {
        label1.Text = NovellUserId.ToString();
      }
      cCode = IcNovell.NWDSFreeContext(NovellContext);
    }
}
}
