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

Compare two ua_compositetesttype structs.
Compares the content of the ua_compositetesttype struct a
to the content of the ua_compositetesttype 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_compositetesttype 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_compositetesttype struct.
Copy all fields from struct ua_compositetesttype 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_compositetesttype 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_compositetesttype struct can also be passed to ua_compositetesttype_compare, ua_compositetesttype_copy and ua_compositetesttype_clear. This function will always succeed as long as an ua_compositetesttype struct is passed to it.
