:"pstat -s" on SunOS4, and "swap -s" on SunOS5. From Solaris man page:
:: -s Print summary information about total swap
:: space usage and availability:
:: allocated The total amount of swap space
:: (in 1024-byte blocks)
:: currently allocated for use as
:: backing store.
:: reserved The total amount of swap space
:: (in 1024-bytes blocks) not
:: currently allocated, but
:: claimed by memory mappings for
:: possible future use.
:: used The total amount of swap space
:: (in 1024-byte blocks) that is
:: either allocated or reserved.
Yah, that's what I thought. A solaris expert could tell us
for sure but I am pretty sure those are simply cached swap
blocks after-the-fact, not actual reservations on potentially
