Hi,

I am trying to recieve a message using SGSocket::read.  
SGSocket::read returns zero bytes read until about the time 
I am expecting the first message to be recieved.  From here on 
SGSocket::read returns that -1 bytes have been read from the socket.
I have looked around (simgear docs, plib) and I cant find out what the 
-1 is supposed to indicate.

Does anyone know?

Seamus
