void ua_eventfieldlist_clear ( struct ua_eventfieldlist t)
related

Clear all resources alloctated in an ua_eventfieldlist struct.

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

int ua_eventfieldlist_compare ( const struct ua_eventfieldlist a,
const struct ua_eventfieldlist b 
)
related

Compare two ua_eventfieldlist structs.

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

int ua_eventfieldlist_copy ( struct ua_eventfieldlist dst,
const struct ua_eventfieldlist src 
)
related

Create a copy of a ua_eventfieldlist struct.

Copy all fields from struct ua_eventfieldlist 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_eventfieldlist_init ( struct ua_eventfieldlist t)
related

Initialize an ua_eventfieldlist 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_eventfieldlist struct can also be passed to ua_eventfieldlist_compare, ua_eventfieldlist_copy and ua_eventfieldlist_clear. This function will always succeed as long as an ua_eventfieldlist struct is passed to it.

static int ua_eventfieldlist_resize_event_fields_array ( struct ua_eventfieldlist val,
int32_t  new_len 
)
related

Resize the event_fields array of a ua_eventfieldlist 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.

Parameters
new_lenNew length of the event_fields array in number of members.
Returns
Zero on success or ua_statuscode on failure.
