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

Compare two ua_contentfilterresult structs.
Compares the content of the ua_contentfilterresult struct a to the content of the ua_contentfilterresult 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_contentfilterresult 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_contentfilterresult struct.
Copy all fields from struct ua_contentfilterresult 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_contentfilterresult 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_contentfilterresult struct can also be passed to ua_contentfilterresult_compare, ua_contentfilterresult_copy and ua_contentfilterresult_clear. This function will always succeed as long as an ua_contentfilterresult struct is passed to it.

Resize the element_diag_infos array of a ua_contentfilterresult 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 element_diag_infos array in number of members. |

| new_len | New length of the element_results array in number of members. |
| element_diag_infos |
A list of diagnostic information for individual elements in the filter.
The size and order of the list matches the size and order of the elements in the filter 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 elements.
| element_results |
A list of results for individual elements in the filter.
