Brian,
 
        You need to use a cast (or type coercion) of the form:
 
        lresult = cix_read_next (base, dset, &jphd, (TYPE) jcx372_proc_entry);
 
where TYPE (in this case) is: int (*) (void *).
 
        Notice that the coercion looks just like the prototype declaration for
param 4 above, except that the identifier is left out.  In general, this is
true for all casts.
 
        Hence your line of code should be:
 
        lresult = cix_read_next (base, dset, &jphd,
                                (int (*) (void *)) jcx372_proc_entry);
 
        The problems you noted with qsort are due to the same problem and
can be fixed in the same manner.
 
        I hope that this helps you.
