for fixed langth, just replace the H5T_VARIABLE with the length you want to set.

I know the length of the string a priori. Can you point me to an example of writing out a fixed length string that uses compression?

Thanks!

        Hi all,

        I'm very new to HDF5 and am trying to find an example of how
        to compress a string written to an HDF5 file.  I've been using
        the C++ API and writing scalar strings to my dataset, but I
        can't figure out how to use data chunking so that I can enable
        compression.


    Variable-length data cannot be compressed due to the way we store
    it in the HDF5 library.

    Dana
