Asynchronous call to delete monitored items.
This Service is used to remove one or more MonitoredItems of a Subscription. When a MonitoredItem is deleted, its triggered item links are also deleted.
Successful removal of a MonitoredItem, however, might not remove notifications for the MonitoredItem that are in the process of being sent by the Subscription. Therefore, Clients may receive notifications for the MonitoredItem after they have received a positive response that the MonitoredItem has been deleted.

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

Compare two ua_deletemonitoreditemsrequest structs.
Compares the content of the ua_deletemonitoreditemsrequest struct a to the content of the ua_deletemonitoreditemsrequest 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_deletemonitoreditemsrequest 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_deletemonitoreditemsrequest struct.
Copy all fields from struct ua_deletemonitoreditemsrequest 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_deletemonitoreditemsrequest 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_deletemonitoreditemsrequest struct can also be passed to ua_deletemonitoreditemsrequest_clear. This function will always succeed as long as an ua_deletemonitoreditemsrequest struct is passed to it.

Resize the monitored_item_ids array of a ua_deletemonitoreditemsrequest 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.
| new_len | New length of the monitored_item_ids array in number of members. |
