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

Compare two ua_variabletypeattributes structs.
Compares the content of the ua_variabletypeattributes struct a to the content of the ua_variabletypeattributes 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_variabletypeattributes 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_variabletypeattributes struct.
Copy all fields from struct ua_variabletypeattributes 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_variabletypeattributes 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_variabletypeattributes struct can also be passed to ua_variabletypeattributes_compare, ua_variabletypeattributes_copy and ua_variabletypeattributes_clear. This function will always succeed as long as an ua_variabletypeattributes struct is passed to it.

Resize the array_dimensions array of a ua_variabletypeattributes 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 array_dimensions array in number of members. |
