- Reserve the pipe NtControlPipe0 for the security process.
- Count regular service control pipes from 1.
- Use I_ScIsSecurityProcess to identify the security process.
- Services.exe uses the SECURITY_SERVICES_STARTED event to notify the security process that NtControlPipe0 is ready for use.
ScControlService:
- SEH-protext the calls to service control handlers.
- Return ERROR_EXCEPTION_IN_SERVICE if a service control handler throws an exception.
- Return ERROR_SERVICE_CANNOT_ACCEPT_CTRL if no service control handler has been registered for the service.
- Set some last errors.
- Fix error code returned by ScLookupServiceByServiceName().
- Check the validity of the handler proc in RegisterServiceCtrlHandler(Ex)W().
- Improve some traces; comment some code.
services\database.c:
- Refactor ScmControlService() so that it can be used to send the dispatcher loop stop command.
- Separate the code to decrement the image run counter from the service image cleanup code.
services\rpcserver.c:
- RSetServiceStatus(): Stop the dispatcher loop when the image run counter is zero and remove the service image after that.
advapi32\service\sctrl.c:
- Do not terminate the service dispatcher loop when the last service is being stopped. Wait for an explicit dispatcher stop command (empty service name).
