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

Compare two ua_cancelrequest structs.
Compares the content of the ua_cancelrequest struct a
to the content of the ua_cancelrequest 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_cancelrequest 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_cancelrequest struct.
Copy all fields from struct ua_cancelrequest 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_cancelrequest 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_cancelrequest struct can also be passed to ua_cancelrequest_clear. This function will always succeed as long as an ua_cancelrequest struct is passed to it.
request_handle |
The request handle assigned to one or more requests that should be cancelled.
All outstanding requests with the matching requestHandle shall be cancelled.
