[Mpi-forum] C++ types inaccessible after #281

[Douglas Miller]

I've got to raise a concern here. If we start defining MPI datatypes to be
C++ types then how will an implementation support that with only a C
compiler? I thought the point of 281 was to eradicate C++ from the standard
(and start over later if C++ was to be defined in the standard).

  There are a few C++-specific datatypes for which it would be worth
  introducing new C datatypes (e.g., MPI_CXX_COMPLEX).  It's too bad that

  deadline.  But it could be part of MPI-3.1 or errata, or some such.

Two people in offline discussions have suggested that C bindings to the
std::complex types (I'm not aware of anything else that #281 will lose)
might qualify as ticket 0._______________________________________________
