void ua_historymodifieddata_clear ( struct ua_historymodifieddata * t )

Frees allocated memory like arrays and resets numeric values. The ua_historymodifieddata struct itself is not freed and must be freed by the caller if required. This function always succeeds for a valid ua_historymodifieddata struct, that was validly decoded, initilized by ua_historymodifieddata_init or created with ua_historymodifieddata_copy.

int ua_historymodifieddata_compare	(	const struct ua_historymodifieddata *	a,
		const struct ua_historymodifieddata *	b
	)

Compares the content of the ua_historymodifieddata struct a to the content of the ua_historymodifieddata 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_historymodifieddata structs, so it is well suited to not only determine equality, but also sort multiple instances of this struct.

int ua_historymodifieddata_copy	(	struct ua_historymodifieddata *	dst,
		const struct ua_historymodifieddata *	src
	)

Copy all fields from struct ua_historymodifieddata 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.

Returns: Zero on success or ua_statuscode on failure.

void ua_historymodifieddata_init ( struct ua_historymodifieddata * t )

After initialization the fields of the struct are set to valid and consistent values and can safley be accessed. An initialized ua_historymodifieddata struct can also be passed to ua_historymodifieddata_compare, ua_historymodifieddata_copy and ua_historymodifieddata_clear. This function will always succeed as long as an ua_historymodifieddata struct is passed to it.

static int ua_historymodifieddata_resize_data_values_array	(	struct ua_historymodifieddata *	val,
		int32_t	new_len
	)

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.

Parameters

new_len New length of the data_values array in number of members.

Returns: Zero on success or ua_statuscode on failure.

static int ua_historymodifieddata_resize_modification_infos_array	(	struct ua_historymodifieddata *	val,
		int32_t	new_len
	)

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.

Parameters

new_len New length of the modification_infos array in number of members.

Returns: Zero on success or ua_statuscode on failure.
