Emilio,

The interface to external functions is written for Fortran, but this
shouldn't prevent you from using C code to do your calculations.  You
only need to write the outline of your function in Fortran and then you
can pass pointers to the data and result to some C subroutine which will
be called from the ~_compute function.  If you've written code which
called C from Fortran before, it should be straightforward.
