At the most recent plugfest, I was introduced to the concept of savepoints
in an active transaction. Going forward I need to implement detection of
savepoint creation and rollback from my mini filter driver. Is there any
detailed implementation notes and or sample code to view with regards to
creating savepoints from the user mode prospective as well as detecting them
from the filter driver. All I can get out of the WDK is the
FSCTL_TXFS_SAVEPOINT_INFORMATION and it’s related structure.
