* Note that these are the back-end functions for MPI_DUP_FN (and
* friends). They have an OMPI_C_* prefix because of weird reasons
* listed in a lengthy comment in mpi.h.
*
* Specifically:
*
* MPI_NULL_DELETE_FN -> OMPI_C_MPI_NULL_DELETE_FN
* MPI_NULL_COPY_FN -> OMPI_C_MPI_NULL_COPY_FN
* MPI_DUP_FN -> OMPI_C_MPI_DUP_FN
*
* MPI_TYPE_NULL_DELETE_FN -> OMPI_C_MPI_TYPE_NULL_DELETE_FN
* MPI_TYPE_NULL_COPY_FN -> OMPI_C_MPI_TYPE_NULL_COPY_FN
* MPI_TYPE_DUP_FN -> OMPI_C_MPI_TYPE_DUP_FN
*
* MPI_COMM_NULL_DELETE_FN -> OMPI_C_MPI_COMM_NULL_DELETE_FN
* MPI_COMM_NULL_COPY_FN -> OMPI_C_MPI_COMM_NULL_COPY_FN
* MPI_COMM_DUP_FN -> OMPI_C_MPI_COMM_DUP_FN
*
* MPI_WIN_NULL_DELETE_FN -> OMPI_C_MPI_WIN_NULL_DELETE_FN
* MPI_WIN_NULL_COPY_FN -> OMPI_C_MPI_WIN_NULL_COPY_FN
* MPI_WIN_DUP_FN -> OMPI_C_MPI_WIN_DUP_FN
