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

Compare two ua_callmethodresult structs.
Compares the content of the ua_callmethodresult struct a to the content of the ua_callmethodresult 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_callmethodresult 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_callmethodresult struct.
Copy all fields from struct ua_callmethodresult 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_callmethodresult 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_callmethodresult struct can also be passed to ua_callmethodresult_compare, ua_callmethodresult_copy and ua_callmethodresult_clear. This function will always succeed as long as an ua_callmethodresult struct is passed to it.

Resize the input_argument_diag_infos array of a ua_callmethodresult 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_argument_diag_infos array in number of members. |

Resize the output_arguments array of a ua_callmethodresult 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 output_arguments array in number of members. |
| input_argument_diag_infos |
List of diagnostic information for each inputArgument.
This list is empty if diagnostics information was not requested in the request header or if no diagnostic information was encountered in processing of the request.
| output_arguments |
List of output argument values.
An empty list indicates that there are no output arguments. The size and order of this list matches the size and order of the output arguments defined by the OutputArguments 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 methods OutputArguments Property.
| status_code |
StatusCode of the method executed in the server.
This StatusCode is set to the Bad_InvalidArgument StatusCode if at least one input argument broke a constraint (e.g. wrong data type, value out of range).
This StatusCode is set to a bad StatusCode if the method execution failed in the server, e.g. based on an exception or an HRESULT.
