In order to use a foreign function, first the dynamic library must be
loaded using the ora_ffi.load_library procedure
fh_mylib:=ora_ffi.load_library(path,filename);
After the library has been loaded the function must be registered in forms
fh_func:=ora_ffi.register_function(fh_mylib,fuction_name,ora_ffi.C_std;
the next step would be to register the parameters for the module in hte
order in which they would appear in the function definition
ora_ffi.register_parameter(fh_func,ORA_FFI.C.INT);
finally the last step needed to register the function is to define the
return value type for the function:
ora_ffi.register_return(fh_func,ora_ffi.c.int);
