This is the p/invoke

        public static void CallBackAuth(IntPtr server,
                                        IntPtr share,
                                        IntPtr workgroup,
                                        int wgmaxlen,
                                        IntPtr username,
                                        int unmaxlen,
                                        IntPtr password,
                                        int pwmaxlen)
        {
            Console.WriteLine("MeeMa");
        }

        public delegate void SmbCGetAuthDataFn(IntPtr server,
                                               IntPtr share,
                                               IntPtr workgroup,
                                               int wgmaxlen,
                                               IntPtr username,
                                               int unmaxlen,
                                               IntPtr password,
                                               int pwmaxlen);


        [DllImport("libsmbclient", CharSet = CharSet.Auto)] extern internal static int smbc_init(SmbCGetAuthDataFn callBackAuth, int debug);
        [DllImport("libsmbclient", CharSet = CharSet.Auto)] extern internal static int smbc_opendir([In, MarshalAs(UnmanagedType.LPStr)]string durl);


Then simple calling into:
    SambaWrapper.SmbInit();
    SambaWrapper.smbc_opendir(@"smb://username:password@somehostname/someshare");


This is the Native code:

typedef void (*smbc_get_auth_data_fn)(const char *srv,                                                                                                                                                                                      
                                      const char *shr,
                                      char *wg, int wglen, 
                                      char *un, int unlen,
                                      char *pw, int pwlen);

int smbc_init(smbc_get_auth_data_fn fn, int debug);                                                                                                                                                                                         
int smbc_opendir(const char *durl);                                                                                                                                                                                                         


This works fine on linux (64 bit) but on OSX it fails with:

  at (wrapper managed-to-native) testnsch.SambaWrapper.smbc_opendir (string) <0xffffffff>
  at testnsch.MainClass.Main (string[]) <0x0002b>
  at (wrapper runtime-invoke) <Module>.runtime_invoke_void_object (object,intptr,intptr,intptr) <0xffffffff>
