Hi, Attached is a binding for libpcap, the packet capture library. I'm looking for comments on how it might be improved, or any particular infelicities that you notice. As I don't use hugs regularly anymore, perhaps someone can point me to a good example of a network library binding that works on both ghc and hugs. It' s tested on FreeBSD (5.2.1-current) but should work with any *nix that can build libpcap. It does not work with Winpcap, a similar library for windows, although it shouldn't be too hard to extend it to do so. The marshalling of packet data is purposely very lightweight (data is returned as Ptr Word8). Having written a lot of embedded software for network test equipment, I prefer the flexibility of being able to marshal into IO-mutable arrays if necessary. But I don't want to impose that on someone who would be satisfied by [Word8]. Best Wishes, Greg Gregory Wright Antiope Associate LLC gwright@antiope.com
