I don't believe you need the '&' operator here, or the '*' operator with
the function call.  For example, if I have a function and a function
pointer:

void a_funtion(char *c);  /* function prototype */
void (*f_ptr)(char *);    /* function pointer */

I can use the function pointer to call the function by:

f_ptr = a_function;
f_ptr("bla bla bla");

Please correct me if I am mistaken.
