** RCBase.h - Mixin class for NSPR C++ wrappers

#if defined(_RCRUNTIME_H)

#include <prerror.h>

** Class: RCBase (mixin)
** Generally mixed into every base class. The functions in this class are all
** static. Therefore this entire class is just syntatic sugar. It gives the
** illusion that errors (in particular) are retrieved via the same object
** that just reported a failure. It also (unfortunately) might lead one to
** believe that the errors are persistent in that object. They're not.
