You need to look in your Fortran manual to find out the details of linking
Fortran to C on your particular system.  (It is almost impossible to give
specific advice without knowing your machine or operating system.)  Often
to call Fortran routine "foobar" you need to call something like "foobar_"
from C.  Also, parameter-passing conventions are often different.  You
usually can't just call Fortran subroutines as if they were C functions.
