Hi Dana, Thanks for your answer! Interesting to hear that there are plans to bring back a windows driver. Any info possible about when it might get funded and implementation time could be scheduled? What would be the differences between a "true" windows driver and the one that was in prior to 1.8.8? I thought of option 2) as well because 1) is nasty since we need the same code base for unix builds as well.

I would say you have two options, assuming you are ok with modifying the HDF5 code and rebuilding the library (as it seems from your email): 1) Just modify the SEC2 driver the way you used to modify the Windows driver. They were basically the same, which was the reason that we tossed the Windows VFD. 2) Copy the SEC2 VFD code, rename it H5FDWindows.c, adjust the internal names to use 'Windows' instead of 'sec2', make your fix, and recompile. A true Windows driver could be written pretty easily, and is at the back of my queue, but is currently unfunded. Also, the stdio code is, in fact, intended to be a demo driver for writing your own VFD (it only uses the public API, not our internal API). It isn't particularly well tested and there are a few open bugs related to external links that have yet to be fixed.
