Deletes all event entries from the history database matching the EventId for one or more HistoricalEventNodes.
If no events are found that match the specified filter for a HistoricalEventNode, the StatusCode for that Node is Bad_NoData.

Clear all resources alloctated in an ua_deleteeventdetails struct.
Frees allocated memory like arrays and resets numeric values. The ua_deleteeventdetails struct itself is not freed and must be freed by the caller if required. This function always succeeds for a valid ua_deleteeventdetails struct, that was validly decoded, initilized by ua_deleteeventdetails_init or created with ua_deleteeventdetails_copy.

Compare two ua_deleteeventdetails structs.
Compares the content of the ua_deleteeventdetails struct a to the content of the ua_deleteeventdetails struct b. If a is smaller than b, an integer less than zero is returned, if a is bigger than b, an integer greater than zero is returned. If both structs are equal zero is returned.
This function creates a total order on ua_deleteeventdetails structs, so it is well suited to not only determine equality, but also sort multiple instances of this struct.

Create a copy of a ua_deleteeventdetails struct.
Copy all fields from struct ua_deleteeventdetails src to dst. Creates a deep copy so all content is recusively copied and both src and dst can be used and must be freed separately.
dst is not cleared before the copy operation, so it must not have any allocated data. It may or may not be initilized by the caller before copy.

Initialize an ua_deleteeventdetails struct with a valid value.
After initialization the fields of the struct are set to valid and consistent values and can safley be accessed. An initialized ua_deleteeventdetails struct can also be passed to ua_deleteeventdetails_compare, ua_deleteeventdetails_copy and ua_deleteeventdetails_clear. This function will always succeed as long as an ua_deleteeventdetails struct is passed to it.

Resize the event_ids array of a ua_deleteeventdetails struct.
Depending on new_len and the current size of the array, the array will be created, increased, decreased or deleted. In case array members are removed these are cleared properly, new array members are initialized with zero.
| new_len | New length of the event_ids array in number of members. |
