Filter callback function definition
typedef int H5Z_filter_t |
Filter identifiers.
Values 0 through 255 are for filters defined by the HDF5 library. Values 256 through 511 are available for testing new filters. Subsequent values should be obtained from the HDF5 development team at help@.nosp@m.hdfg.nosp@m.roup..nosp@m.org. These values will never change because they appear in the HDF5 files.
