Modes for ex_set_option()

The compression-related options are only available on netcdf-4 files since the underlying hdf5 compression functionality is used for the implementation. The compression level indicates how much effort should be expended in the compression and the computational expense increases with higher levels; in many cases, a compression level of 1 is sufficient.

Enumerator
EX_OPT_MAX_NAME_LENGTH	Maximum length of names that will be returned/passed via api call.
EX_OPT_COMPRESSION_TYPE	Not currently used; default is gzip
EX_OPT_COMPRESSION_LEVEL	In the range [0..9]. A value of 0 indicates no compression
EX_OPT_COMPRESSION_SHUFFLE	1 if enabled, 0 if disabled
EX_OPT_INTEGER_SIZE_API	4 or 8 indicating byte size of integers used in api functions.
EX_OPT_INTEGER_SIZE_DB	Query only, returns 4 or 8 indicating byte size of integers stored on the database.
