simultaneously reading hdf4 and hdf5

Hello,
Some of the datasets that I need to process together are formatted in hdf4
and some in hdf5. I am trying to use a fortran interface to do that but h5
routine calls fail to read h4 files. What is the best way to solve this
problem?
(I compile the code with h5fc)
Thanks,
Mark

Hello,

HDF4 file format is different from HDF5. HDF5 library cannot read HDF4 files. You will need to use APIs from both HDF4 (https://www.hdfgroup.org/products/hdf4/) and HDF5 if you are working with two types of the HDF files.

Probably a better approach would be to use the h4toh5 conversion tool (https://www.hdfgroup.org/h4toh5/) to convert HDF4 files to HDF5 and use the HDF5 library.
