/**
 * \defgroup H5ES H5ES
 * \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
