[mpiwg-tools] question about MPI_T_EVENT_GET_INFO

[Martin Schulz]

Hi Ken,

Thanks for pointing this out - I think you are correct. At least on the PVAR side, that's how it was intended. I would assume, the same should be true for the events as well - Marc-Andre, do you agree?

Thanks,

Martin

    Hi all,

    In the latest mpi-4.0 RC pg 758, ln 16 describing MPI_T_EVENT_GET_INFO:

       If the argument to enumtype provided by the user is the MPI_T_ENUM_NULL pointer, no enumeration type is returned.

    This differs from previous get info functions. E.g. MPI_T_PVAR_GET_INFO:

       ... or the argument enumtype is the null pointer, no enumeration type is returned.

    IMO, the user providing MPI_T_ENUM_NULL to enumtype doesn't make sense. The user would pass a null pointer, as it is an output argument.
