Re: Event driven CFStream protocol in 10.1?

Thank you for the assistance. The requirement for exclusive ownership of the
file descriptor was lost on me. Because CFStreamCreatePairWithSocketToHost
is asynchronous if the address is a dotted four, there isn't a need for me
to use CFSocket at all, which is great!
