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

Compare two ua_eventfilterresult structs.
Compares the content of the ua_eventfilterresult struct a to the content of the ua_eventfilterresult 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_eventfilterresult 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_eventfilterresult struct.
Copy all fields from struct ua_eventfilterresult 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_eventfilterresult 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_eventfilterresult struct can also be passed to ua_eventfilterresult_compare, ua_eventfilterresult_copy and ua_eventfilterresult_clear. This function will always succeed as long as an ua_eventfilterresult struct is passed to it.

Resize the select_clause_diag_infos array of a ua_eventfilterresult 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 select_clause_diag_infos array in number of members. |

| new_len | New length of the select_clause_results array in number of members. |
| select_clause_diag_infos |
A list of diagnostic information for individual elements in the select clause.
The size and order of the list matches the size and order of the elements in the selectClauses request parameter. This list is empty if diagnostics information was not requested in the request header or if no diagnostic information was encountered in processing of the select clauses.
| select_clause_results |
List of status codes for the elements in the select clause.
The size and order of the list matches the size and order of the elements in the selectClauses request parameter. The Server returns null for unavailable or rejected Event fields.
