[boost] [asio] Read timeout and failures

Subject: [boost] [asio] Read timeout and failures

I'm running boost v1.45 on WindowsXP SP3

I've read all the stuff on using async reads if you want a timeout and I'm going to switch to the from my current synchronous read code.

However, I have a question regarding failures.  I have been using a synchronous read_some() call.  This states that it will return/throw an error/exception on an error condition.  If I'm connected on a TCP socket to another device and I UNPLUG the network cable, does this not shutdown the socket and shouldn't the read_some() return/throw an error/exception.  Unplugging the cable seems like an error condition to me, but in my case, the code just hangs at the read_some() call and never returns.

Thanks,
