Have you considered the C++ way with io streams?
That would be my preferred approach, but it would break the current
interface.
Or it might be solvable using C++11 variadic templates?
Maybe, but I'd prefer a simpler solution if possible.
I'm not sure I understand the problem though.
In a nutshell, the use of ellipses in functions like dolfin_error mean
that we cannot overload the function, e.g. it doesn't appear possible
to do:
void dolfin_error(std::string location,
std::string task,
std::string reason, ...);
void dolfin_error(MPI_Comm mpi_comm,
std::string location,
std::string task,
std::string reason, ...);

We have some very C-like (and not C++ like) code in the DOLFIN
logging that uses ellipses to take a variable number of arguments,
e.g in dolfin/log/log.h. I'm trying to straighten out logging in
parallel by passing an MPI communicator to the log functions, but I
can't re-use function names because of the ellipses. Does anyone
know a better solution than using ellipses, or have suggestions on
getting around the problem?
