Thanks. What are they for? My concern is that _SC_AVPHYS_PAGES isn't going to semantically match other platforms since in a steady state the free count is small on FreeBSD, but on other systems it swings quite a bit based on load. +Note that it is possible for the product of this value and the value of +.Li _SC_PAGE_SIZE +to overflow. This would be more clear if it said what was expected to overflow and when. -- Brooks [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (FreeBSD) iD8DBQFFSPSJXY6L6fI4GtQRAnjIAJkBi5yCmmG8FWD40IwzTcCWl+EhxQCgi1ti gVBnIKnJHqRkGsMAh6cK5iM= =fCSN -----END PGP SIGNATURE-----home | help
