MPI-3.1 Figure 17.1 (in section 17.2.5, starting on page 656) defines the following routines:
1. MPI_Status_c2f() (from MPI-2)
2. MPI_Status_f2c() (from MPI-2)
3. MPI_Status_c2f08() (new in MPI-3)
4. MPI_Status_f082c() (new in MPI-3)
5. MPI_Status_f2f08() (new in MPI-3)
6. MPI_Status_f082f() (new in MPI-3)
All of the functions are fairly straightforward to implement in C.
But per the bottom part of Figure 17.1, two of the routines are supposed to be implemented in Fortran: #5 and #6.
Does this mean that TYPE(MPI_Status) needs to be defined in mpif.h and the mpi module?
I'm not sure how an MPI application would be able to invoke functions #5 and #6 without a definition of TYPE(MPI_Status) -- or even have a variable of that type that they need to convert to INTEGER(MPI_STATUS_SIZE).
