Detailed Description

Register callbacks that get triggered on SIGINT and SIGTERM.

This class is a thread-safe interface to system signals (SIGINT and SIGTERM). Use the AddCallback(std::function<void(int)>) function to register callbacks that should be called when a SIGINT or SIGTERM is triggered.

Example using a lambda callback:

ignition::common::SignalHandler handler;
handler.AddCallback([] (int _sig)
{
  printf("Signal[%d] received\n", _sig);
});
