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

Compare two ua_transferresult structs.
Compares the content of the ua_transferresult struct a to the content of the ua_transferresult 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_transferresult 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_transferresult struct.
Copy all fields from struct ua_transferresult 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_transferresult 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_transferresult struct can also be passed to ua_transferresult_compare, ua_transferresult_copy and ua_transferresult_clear. This function will always succeed as long as an ua_transferresult struct is passed to it.

Resize the available_sequence_numbers array of a ua_transferresult 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. |
| available_sequence_numbers |
A list of sequence number ranges that identify NotificationMessages that are in the Subscription’s retransmission queue.
This parameter is null if the transfer of the Subscription failed.
