Mathieu, don't worry about the chunks. Just read/write what you need
in terms of the dataspace (hyperslab, point selection...) and the library
will determine for you which chunks are touched (read/written) by the
operation.
It'll just return fill values for un-allocated/partially filled chunks.
Yep you're right! But the time to read the data is linear with the size
of all the Dataset, not only of the size of available data !
My real dataset is really sparse ! i need to read all available value
without taking time to read unavailable value.
Is there anyway to select only real value?
Anyway how to know how many value are really read from dataset?
Thanks

Best, G.

Subject: [Hdf-forum] Read All Available Chunk in a Dataset.
I have a dataset of size 16*16
I write Chunk of Data of size 4*4.
Some data aren't available so i wrote only 3 chunk on my dataset.
How to read only the 3 available chunk?
Thanks
Mathieu
