Flushing file

[kiranshila]

Hello again! Another quick issue/question -

Is there an equivalent to nc_sync / flushing to disk in this rust implementation? I'm getting some errors occasionally that look like

HDF5.API.H5Error: Error reading dataset /voltages
libhdf5 Stacktrace:
  [1] H5FD_read: Invalid arguments to routine/Address overflowed
      addr overflow, addr = 16803176, size = 3656, eoa = 16803176

when trying to read from other programs. Looking around this seems to be the result of an incomplete write.

We should expose nc_sync to allow the user to sync the file. In the mean time you could use open_with with the SHARE flag.

Can you get the native handle to call nc_sync on it? I couldn't spot it in the docs.

[mulimoen]

No, the native handle is kept private

It should be mentioned that reading a file whilst writing to it is not supported by hdf5 unless SWMR mode is set. There is a PR implementing this in netcdf-c here: Unidata/netcdf-c#2653

@kiranshila This is published in 0.9.1 and can be called as FileMut::sync.

Fantastic, beat me to the PR. Thank you so much!
