Direct, low-level interface to the system MPI library.
This low-level interface provides direct access to the unmanaged
MPI library provided by the system. It is by nature unsafe, and
should only be used by programmers experienced both in the use
of MPI from lower-level languages (e.g., C, Fortran) and with an
understanding of the interaction between managed and unmanaged
code, especially those issues that pertain to memory
pinning/unpinning.
The Unsafe..::.MPI_Status type exposes the following members.
