the VFS equipped resource locking dont force you to call DmReleaseResource
tho :) thats the problem. ideally, this is what the API would be used
for :) but, it isn't :)
i just wrote a simple library to:
- open database/file
- get resource
- release resource
- close database/file
so that it is transparent between ram + vfs. :) [needed that for lemmings]
