Fill value


When applying the function "H5Pset_fill_value" to a new dataset of type variable-length string, the fill value is written properly in this new dataset.

However, if the dataset is of type variable-length int (in fact, any type except string), it doesn't set the fill value in this new dataset.

Any idea of what is happening?

Also, it seems that the function "H5Pset_fill_value" is innocuous (i.e. it is not considered) when creating attributes. Is it true? If so, what is the

Thank you,
