Asynchronously deletes nodes from the OPC UA server’s address space.
If any of the Nodes deleted by an invocation of this service is the target node of a reference, those references are left unresolved based on the deleteTargetReferences parameter.
If any of the nodes deleted by an invocation of this service is being monitored, a notification containing the status code Bad_NodeIdUnknown is sent to the monitoring Client indicating that the node has been deleted.

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

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

Resize the nodes array of a ua_deletenodesrequest 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 nodes array in number of members. |
