Then, I would expect, this ticket is simple and a self-explaining good and ***necessary*** extension for MPI-next.
Exactly this rational is the basis that all C programming Forum members will see the necessity.
Eh? I assuredly count as one of them, and I don't see the necessity. Over a decade ago, I decided that it was a mistake for MPI to pass arguments to MPI_Init in C, and it was done only to make life easier for some rather PVM-like implementations. I would have preferred MPI to say "Tough. Implementations must pass MPI's options in some way that does not affect the user's argument list." The MPI 2.0 C++ interface people seemed to think the same. Regards, Nick Maclaren.
