I normally open a dataspace with H5Dget_space, then use the H5Sget_simple_extent_ndims and H5Sget_simple_extent_dims to get the dimensionality and dimensions..
This example http://www.hdfgroup.org/ftp/HDF5/examples/examples-by-api/hdf5-examples/1_8/C/H5D/h5ex_d_unlimadd.c illustrates this. I think you can also use H5Dget_storage_size directly if you don't care about the array structure (or if it's 1D) and just want to dump the data. -John _______________________________________________ Hdf-forum is for HDF software users discussion.
