Specifies a different prefix to avoid name collisions.
Low-level properties and methods are exposed by member functions named with a default prefix of raw_ to avoid name collisions with the high-level error-handling member functions.
The effects of the raw_method_prefix attribute will not be changed by the presence of the raw_interfaces_only attribute. The raw_method_prefix always takes precedence over raw_interfaces_only in specifying a prefix. If both attributes are used in the same #import statement, then the prefix specified by the raw_method_prefix attribute is used.
