* \todo Add the event set life cycle.
*
* \brief Event Set Interface
*
* \details \Bold{This interface can be only used with the HDF5 VOL connectors that
* enable the asynchronous feature in HDF5.} The native HDF5 library has
* only synchronous operations.
*
* HDF5 VOL connectors with support for asynchronous operations:
* - ASYNC
* - DAOS
*
* \par Example:
* \code
* fid = H5Fopen(..);
* gid = H5Gopen(fid, ..); //Starts when H5Fopen completes
* did = H5Dopen(gid, ..); //Starts when H5Gopen completes
*
* es_id = H5EScreate(); // Create event set for tracking async operations
* status = H5Dwrite_async(did, .., es_id); //Asynchronous, starts when H5Dopen completes,
* // may run concurrently with other H5Dwrite_async
* // in event set.
* status = H5Dwrite_async(did, .., es_id); //Asynchronous, starts when H5Dopen completes,
* // may run concurrently with other H5Dwrite_async
* // in event set....
* <other user code>
* ...
* H5ESwait(es_id); // Wait for operations in event set to complete, buffers
* // used for H5Dwrite_async must only be changed after wait
* // returns.
* \endcode
