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

Compare two ua_historyupdatedetails structs.
Compares the content of the ua_historyupdatedetails struct a
to the content of the ua_historyupdatedetails 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_historyupdatedetails 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_historyupdatedetails struct.
Copy all fields from struct ua_historyupdatedetails 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_historyupdatedetails 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_historyupdatedetails struct can also be passed to ua_historyupdatedetails_compare, ua_historyupdatedetails_copy and ua_historyupdatedetails_clear. This function will always succeed as long as an ua_historyupdatedetails struct is passed to it.
