The normal way to do this is simply to try a non-blocking receive. If there is any data to receive, you need to get that data anyway, so you might as well do both things in the same step. It is unusual to say "I don't want to receive any data on this connection if there is any, but I want to know what condition it's in". If you know that there can't be any data (because of the protocol), you can still try a read. If you get 'would block' you know the connection is fine. If you get an error or you get data, you know something is wrong.
