sc_trace for all sc_signal,sc_in, sc_out

Hi,

I have a query regarding sc_trace.

Is it possible to have directly get all the signals and ports dumped into the VCD file.

I am trying something like this in sc_main:

Top top1("top1");

sc_trace_file *tf = sc_create_vcd_trace_file("waveforms");
sc_simcontext *context = sc_get_curr_simcontext();
sc_object *optr = context->first_object();
while(optr) {
    if (std::string(optr->kind()) == "sc_signal") optr->trace(tf);        
    optr = context->next_object();
    }

With this I am not getting anything into the waveforms.vcd.

Could anyone please suggest the correct way to do the above.

Thanks for the help.
