Detailed Description

C++ wrapper for runtime options.

Provides a convenient C++ interface to LibrpaOptions with constructor initialization and setter methods.

Note

Straightforward inheritance. DO NOT add extra member variables here, which will break the inherited data layout. New control options should be put under the LibrpaOptions C structure.
