Member Function Documentation
   virtual const char * std::runtime_error::what () const [virtual],
       [noexcept],  [inherited]
       Returns a C-style character string describing the general cause of the
       current error (the same string passed to the ctor).


       Reimplemented from std::exception.

       Reimplemented in std::experimental::filesystem::v1::filesystem_error,
       and std::filesystem::filesystem_error.
