This function is internal to Open MPI, and is therefore not prototyped in
mpi.h. You can call any function in libmpi that you want (including
ompi_op_reduce), but you'll need to either prototype it yourself or
configure Open MPI with --with-devel-headers that will allow you to include
"ompi/op/op.h", where it is prototyped.
However, I'd advise against this for the following reasons:
- your code will be non-portable
- it's not a public function, and is therefore subject to change at any time
(i.e., we may change its prototype, how it works, etc. -- this is unlikely,
but certainly possible)
