This example creates a chunked and ZLIB compressed dataset. It also includes comments for what needs to be done to create an SZIP compressed dataset. The example then reopens the dataset, prints the filter information, and reads the dataset:

The H5PsetH5P_deflate SET_DEFLATE call modifies the Dataset Creation Property List instance to use ZLIB or DEFLATE compression. The H5Pset_szip call modifies it to use SZIP compression. There are different compression parameters required for each compression method.
SZIP compression can only be used with atomic datatypes that are integer, float, or char. It cannot be applied to compound, array, variable-length, enumerations, or other user-defined datatypes. The call to H5Dcreate H5D_CREATE will fail if attempting to create an SZIP compressed dataset with a non-allowed datatype. The conflict can only be detected when the property list is used.
There are restrictions for use of SZIP by commercial users. See the documents at SZIP Compression in HDF5 for further information on SZIP, including the SZIP copyright notice.
