H5ES_WAIT waits for operations in an event set es_id to wait with timeout.

Timeout value is in nanoseconds, and is for the H5ESwait call and not for each individual operation in the event set. For example, if "10" is passed as a timeout value and the event set waited 4 nanoseconds for the first operation to complete, the remaining operations would be allowed to wait for at most 6 nanoseconds more, i.e., the timeout value used across all operations in the event set until it reaches 0, then any remaining operations are only checked for completion, not waited on.

This call will stop waiting on operations and will return immediately if an operation fails. If a failure occurs, the value returned for the number of operations in progress may be inaccurate.

Returns a non-negative value if successful; otherwise returns a negative value.
