Constructor & Destructor Documentation

~Handler()

virtual Cpl::System::Shutdown::Handler::~Handler ( )

inlinevirtual

Ensure the destructor is virtual.

Member Function Documentation

notify()

virtual int Cpl::System::Shutdown::Handler::notify ( int  exit_code )

pure virtual

This method is called when the application is shutting down.

The method is passed 'exit_code' which is the exit code provided by the application when called the Shutdown interface. The return value from the handler will be used as the application shutdown exit code. To leave the exit code unaltered - return the passed in 'exit_code'.

Notes:

o The final exit code is the serialized 'sum' of the all of the
  shutdown handlers.
o The notify() method is called in the thread context that
  initiated the shutdown.
