Yes, of course you can interface the function from C.  There are some hints 
how to write the exact interface prototypes for your C/C++ function 
declaration on the `info g77' info pages.

You should try to use f2c to generate your interfaces at least for the first 
time.  See the hints on the info pages:

# info g77 "Other Languages" "Interoperating"

There you will find all you need !
