re: https://github.com/Unidata/netcdf-c/issues/972 The current szip plugin code in the HDF5 library has some unexpected behaviors that require some changes to how nc_inq_var_szip is implemented and to the corresponding tests: nc_test4/{test_szip,tst_vars3}. Specifically, the following can happen: 1. The number of parameters provided by the user will be two, but the number of parameters returned by nc_inq_var_filter will be four because the HDF5 code (H5Zszip) will add two extra parameters for internal use. It turns out that the two parameters provided when calling nc_def_var_filter correspond to the first two parameters of the four parameters returned by nc_inq_var_filter. 2. The nc_inq_var_szip values corresponding to the ones provided by the caller may be different than those provided by nc_def_var_filter. The value of the options_mask argument is known to add additional flag bits, and the pixels_per_block parameter may be modified.
