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

Compare two ua_publishresponse structs.
Compares the content of the ua_publishresponse struct a to the content of the ua_publishresponse 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_publishresponse 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_publishresponse struct.
Copy all fields from struct ua_publishresponse 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_publishresponse 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_publishresponse struct can also be passed to ua_publishresponse_clear. This function will always succeed as long as an ua_publishresponse struct is passed to it.

Resize the available_sequence_numbers array of a ua_publishresponse 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 available_sequence_numbers array in number of members. |

Resize the diag_infos array of a ua_publishresponse 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 diag_infos array in number of members. |

Resize the results array of a ua_publishresponse 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 results array in number of members. |
| available_sequence_numbers |
A list of sequence number ranges that identify unacknowledged NotificationMessages that are available for retransmission from the Subscription’s retransmission queue.
This list is prepared after processing the acknowledgements in the request.
| diag_infos |
List of diagnostic information for the acknowledgements.
The size and order of the list matches the size and order of the ua_PublishRequest::subscription_acknowledgements 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 request.
| more_notifications |
A Boolean parameter indicating whether all avalaible notifications could be included in a single response.
It has the following values:
| results |
List of results for the acknowledgements.
The size and order of the list matches the size and order of the ua_PublishRequest::subscription_acknowledgements request parameter.
| subscription_id |
The Server-assigned identifier for the Subscription for which notifications are being returned.
The value 0 is used to indicate that there were no Subscriptions defined for which a response could be sent.
