Hi, Douglas By reading SCL 1.3.8 documents, I saw the TIMEOUT keyword in EXT:CONNECT-TO-INET-SOCKET, so I guess just use this keyword will be OK to add support for TIMEOUT in USOCKET:SOCKET-CONNECT. more questions:
1. From which version of SCL, the TIMEOUT keyword be added? All SCL version or there's some way we can detect whether TIMEOUT can be used? (i.e *features*, fboundp, ...) 2. How to support DEADLINE in SCL? (I can find details from SCL doc) 3. What if we (usocket) don't split out DEADLINE from SOCKET-CONNECT but add a new SET-SOCKET-OPTION to set the behavior of a already created socket?
