Hi,

are there any concrete plans to support timeouts in usocket? CL implementations begin to provide both relative timeouts or absolute deadlines in their low level socket implementations, and it would be nice to be able to use them without having to resort to hacking usocket in application specific ways.

Absolutely. (Sorry btw for the long time it took me to respond!)

If it's possible to implement a time-out to calls which currently don't, that would be great! Please note that you can model read-timeouts through the WITH-INPUT-AVAILABLE macro. It would be even nicer to be able to extend that macro with support for SOCKET-CONNECT and possibly other operations (such as write-waiting?).

In particular, SOCKET-CONNECT needs a timeout argument.

Yes, it does.

If there are no current plans, I'll add timeouts to my list and add them.

Well, if you could do the research (ie: tell me for the most relevant CL implementations what the APIs are), I'll gladly implement the timeouts.

Hope that answers your question.

Bye,

Erik.
