I finally managed to get a version of syncOpen() working -- this has already been requested in issue #26.
The behaviour is exactly equal to the async version, I just put all the code from OpenAsync into the new static function syncOpen. It throws an exception on error.
I also wrote a rudimentary unit test for syncOpen() that simply tests if the handle returned passes a simple put/get test.
Merging would be highly appreciated as this feature has been requested repeatedly.
Added unit tests for syncOpen
Sorry, that took to so long. I had a funeral and lost track for a bit. Thanks for the great update.
4 days is really fast IMO ;-) Thanks for merging!
