Single Unix Specification v3 specifies only AF_* constants, used for both. Linux man socket says: NOTE The manifest constants used under BSD 4.* for protocol families are PF_UNIX, PF_INET, etc., while AF_UNIX etc. are used for address fami- lies. However, already the BSD man page promises: "The protocol family generally is the same as the address family", and subsequent standards use AF_* everywhere. -- __("< Marcin Kowalczyk \__/ [EMAIL PROTECTED] ^^ http://qrnik.knm.org.pl/~qrczak/ _______________________________________________ Haskell mailing list Haskell@haskell.org http://www.haskell.org/mailman/listinfo/haskell
