how to know if socket is still connected

[nephish at xit.net]

oh, sorry, what i mean by dropped is that the server i am connecting to
can close the connection. If that happens, i need to know about it.
i also need to know about it if the server i am connecting to just
dies.

if recv() returns "" is that the same as NONE ?
again, sorry, i am still kinda new at this.
I mean can the value be tested true or false?

thanks
