Hi There,
I currently use the P/Invoke declarations for the HDF C-API in .NET.
However I am struggling to convert the pointer values to their actual
values from the HDF file.
I have attached a screen shot of my code and the AccessViolationException I
am getting.
Can you kindly give me indication where I am going wrong ?
I know this kind of exception are common in .NET when working with
unmanaged libraries.
Kind Regards.
Johan Ferguson
I would think you’d want the entire HDF5 (parallel) test suite to run correctly on it, assuming that is the intended outcome and its practical to test.

Subject: [Hdf-forum] validating a vfl plugin
I’ve written a plugin for the virtual file layer that uses an I/O library, which is a parallel I/O library, similar to MPI-IO. I’ve modified the ph5example.c to work with my plugin and all the tests pass. Which other tests may be useful in validating such a plugin? Thanks.
Sorry, that probably came across as somewhat flipint.
I was *assuming* that the whole HDF5 test suite can be easily run on various VFDs and/or with various FAPL/FCPL in a genral way so that it doesn’t require modifying each and every test client. That is what I do with Silo library 
But, I don’t know that to actually be the case and in all likelihood, it is probably not. So, that’d mean you have a lot of test clients to modify (and not all of them actually test format operations — for example the data conversion tests don’t).
Note to The HDF Group: It would really be good to be able to run the entire HDF5 test suite using different FAPLs/FCPLs. It would make this kind of testing much simpler

Mark,
It doesn't seem like the test suite can be easily run on various VFDs in a general way. So, I was wondering which tests would be the most relevant.
