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

Compare two ua_callmethodrequest structs.
Compares the content of the ua_callmethodrequest struct a to the content of the ua_callmethodrequest 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_callmethodrequest 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_callmethodrequest struct.
Copy all fields from struct ua_callmethodrequest 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_callmethodrequest 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_callmethodrequest struct can also be passed to ua_callmethodrequest_compare, ua_callmethodrequest_copy and ua_callmethodrequest_clear. This function will always succeed as long as an ua_callmethodrequest struct is passed to it.

Resize the input_arguments array of a ua_callmethodrequest 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 input_arguments array in number of members. |
| input_arguments |
List of input argument values.
An empty list indicates that there are no input arguments. The size and order of this list matches the size and order of the input arguments defined by the input InputArguments Property of the method.
The name, a description and the data type of each argument are defined by the Argument structure in each element of the method’s InputArguments Property.
| method_id |
NodeId of the method to invoke.
If the objectId is the NodeId of an object, it is allowed to use the NodeId of a method that is the target of a HasComponent Reference from the ObjectType of the object.
| object_id |
The NodeId shall be that of the object or ObjectType that is the source of a HasComponent Reference (or subtype of HasComponent Reference) to the method specified in methodId.
See Part 3 of the OPC UA Specification for a description of objects and their methods.
