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

Compare two ua_browseresult structs.
Compares the content of the ua_browseresult struct a to the content of the ua_browseresult 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_browseresult 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_browseresult struct.
Copy all fields from struct ua_browseresult 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_browseresult 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_browseresult struct can also be passed to ua_browseresult_compare, ua_browseresult_copy and ua_browseresult_clear. This function will always succeed as long as an ua_browseresult struct is passed to it.

Resize the references array of a ua_browseresult 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 references array in number of members. |
| references |
The set of references that meet the criteria specified in the BrowseDescription.
Empty if no references met the criteria.
| status_code |
The status for the BrowseDescription.
This value is set to Good if there are still references to return for the BrowseDescription.
