Hello, I am trying to re-create the types below from an Hdf5 file created by another software package (output below was generated from h5dump) but am not quite sure on how to define them. I am using h5dotnet wrappers (though c examples would help). 1) This appears to be a fixed-length string. It seems straightforward enough, but the h5dotnet docs suggest using ascii character arrays which give a different type signature. Any reason the h5t_c_s1 type cannot be used in c#? 2) Not clear what this type is and how the sizes are specified or mean. May be the following C examples will help. For the fixed size attribute type please see http://www.hdfgroup.org/ftp/HDF5/examples/examples-by-api/hdf5-examples/1_8/C/H5T/h5ex_t_stringatt.c. Please replace lines filetype = H5Tcopy (H5T_FORTRAN_S1); status = H5Tset_size (filetype, SDIM - 1); with filetype = H5Tcopy (H5T_C_S1); status = H5Tset_size (memtype, SDIM); to get the type similar to yours. For the second type, please see http://www.hdfgroup.org/ftp/HDF5/examples/examples-by-api/hdf5-examples/1_8/C/H5T/h5ex_t_vlenatt.c. You will need to use H5T_C_S1 base type in the H5Tvlen_create calls and play with data initialization. Please let me know if you need further help.
