Enum with doubled entries

Hdf-forum archives

Hi,
I ran into an issue with the enum interface :
In C this is allowed :
     enum frame_mode_t {
         RAW_MODES = 128,
         MODE_BAYER = RAW_MODES,
     };

For HDF5 this would give me an
H5T_enum_insert(): value redefinition

Any opinions on this issue ?

From my point of view this is a bug in HDF5.

Enums have not been very precisely defined in HDF5. It's in my queue to
address that in the future. I'm not sure when that will happen since there
is no funding source for that work, but I'd like to get an RFC out to the
community as soon as I can find a spare moment.

Cheers,

Dana
