The easy answer is yes.  You can call both Fortran and C MPI routines
inside a single program.  There are a number of issues involved.  In
MPI-2 the issue of language interoperability was considered more
formally and in more detail.  You might find it useful to look at
section 4.12 of the MPI-2 document (http://www.mpi-forum.org).  Some
of the issues are: is the data representation the same for the MPI
datatypes, are constants the same, etc.

Good luck,
Steve
