Hi,
Currently the HDF5 FAQ says about bitfields ...
How are these stored then? Any sort of padding or what?
We currently do not pack them, so a 13-bit field in a 32-bit
datatype still takes up 4 bytes of space. This is not ideal, but
it is a fairly complicated problem to pack the bits on disk (in
light of using bitfields in compound, array and variable-length
datatypes mostly). Eventually we should fix this.
Is there any plan to implement packed bit fields in the near
future?
Thanks,
Steve
