raw_interfaces_only
C++ Specific
Suppresses the generation of error-handling wrapper functions and property (C+) declarations that use those wrapper functions.
raw_interfaces_only
Remarks
The raw_interfaces_only attribute also causes the default prefix used in naming the non-property functions to be removed. Normally, the prefix is raw_. If this attribute is specified, the function names are directly from the type library.
This attribute allows you to expose only the low-level contents of the type library.
