Hi John,

In article <6c65f9$6be@smc.vnet.net>, John Fultz <jfultz@wolfram.com>

I check MLNumber() by a small program. It is not a socket number but a
some internal number, I don't know what it is.

void testopen()
{
   long err;
   tlink = MLOpenString(stdenv, "-linkmode listen -linkprotocol TCP
-linkoptions MLDontInteract", &err);
   MLPutFunction(stdlink, "List", 2);
   MLPutString(stdlink, MLName(tlink));
   MLPutLongInteger(stdlink, MLNumber(tlink));
   MLEndPacket(stdlink);
}

In[42]:=testOpen[]
Out[42]={"2083@192.168.0.2",4}

bye.
