[ace-users] Svc Termination

[JR Andreassen]

Hi...
 Yes that does the trick.
My intent is to terminate the service.

So that gives me the following sequence for terminating the Service:

I do a "broadcast" with a SIGTERM 
    => calls:  handle_signal(SIGTERM)
        => causes all SVC's to terminate their loop.
                and does a join[wait()]
    => ACE_Service_Config::fini_svcs(); -> cleanup...
---------------------------------------------
Like such:
void SDI_ACENTService::handle_control (DWORD control_code)
{
  if (control_code == SERVICE_CONTROL_SHUTDOWN
      || control_code == SERVICE_CONTROL_STOP)
    {
        report_status (SERVICE_STOP_PENDING);
        SDI::GlobalDebug::Log("SDI_ACENTService control stop requested");
        SDI::ACE_Utils::broadcastSignal(SIGTERM, 0);
        ACE_Service_Config::fini_svcs();
        ACE_Reactor::instance()->end_reactor_event_loop();
        stop_ = 1;
    }
  else
  {    super::handle_control (control_code);}
}


Thanks for the input.

P.S. I have extended "ACE_NT_Service" to include "standard" registry 
interface as well, if there is intrest I'll contribute it...
