INET-domain sockets
-
-The TCP and UDP sockets that you know and love. Some representation issues:
-
-- These functions do not accept hostnames directly: see name resolution
-
- Internet addresses are represented by vectors of (unsigned-byte 8) - viz. #(127 0 0 1). Ports are just integers: 6010. No conversion between network- and host-order data is needed from the user of this package.
-
- socket addresses are represented by the two values for address and port, so for example, (socket-connect s #(192 168 1 1) 80)
