form. Subscriptions are regular expressions.
. different types are stored per key; currently u32 and/or string.
the same key can be referenced (publish, subscribe, check) as any type.
. notify()s are sent when subscriptions are triggered (publishing or
updating of matching keys); optionally, a subscribe flag sends
updates for all matching keys at subscription time, instead of only
after updates after subscribing
. all interfacing to ds is in /usr/src/lib/syslib/ds.c.
. subscribe is ds_subscribe
publish functions are ds_publish_<type>
retrieve functions are ds_retrieve_<type> (one-time retrieval of a value)
check functions are ds_check_<type> (check for updated key caller
subscribes to not yet checked for, or ESRCH for none)
. ramdisk driver updated with new ds interface
