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

Compare two ua_subscriptionacknowledgement structs.
Compares the content of the ua_subscriptionacknowledgement struct a to the content of the ua_subscriptionacknowledgement 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_subscriptionacknowledgement 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_subscriptionacknowledgement struct.
Copy all fields from struct ua_subscriptionacknowledgement 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_subscriptionacknowledgement 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_subscriptionacknowledgement struct can also be passed to ua_subscriptionacknowledgement_compare, ua_subscriptionacknowledgement_copy and ua_subscriptionacknowledgement_clear. This function will always succeed as long as an ua_subscriptionacknowledgement struct is passed to it.
| sequence_number |
The sequence number being acknowledged.
The Server may delete the message with this sequence number from its retransmission queue.
