[SDL] How to know when SDLNet_TCP_Recv has no more data available, or how to specify timeout for it?

[necronology at cox.net]

It's my understanding that most would use something like:
if (SDLNet_TCP_Recv(sd, (char*)buffer, 512)) so in your main loop you check to see if there is something to pick up and the answer is yes or no. You do have the choice not to check or to close out that sd. Is this what you mean by waiting?
