Set padding type for least and most significant bits
H5T.set_pad(type_id,lsb,msb)
H5T.set_pad(type_id,lsb,msb) sets the padding type for the least and
most-significant bits. type_id is the identifier of the data type.
lsb specifies the padding type for least-significant bits;
msb for most-significant bits. Specify padding types as one of
these character vectors or string scalars: 'H5T_PAD_ZERO',
'H5T_PAD_ONE', or 'H5T_PAD_BACKGROUND' (leave
background alone).
type_id = H5T.copy('H5T_NATIVE_INT'); lsb = H5ML.get_constant_value('H5T_PAD_ONE'); msb = H5ML.get_constant_value('H5T_PAD_ZERO'); H5T.set_pad(type_id,lsb,msb);
