mio::WatchDog Class Reference

Detailed Description

A software watchdog, killing the current process after the given number of seconds.

On Posix systems (Linux, MacOS), this is implemented with a call to alarm() that will emit the SIGALRM signal after the provided number of seconds. A signal handler is declared that throws an exeption when the SIGALRM signal is caught, so a stack trace can be printed before exiting.

On Microsoft Windows, this is implemented as a QueueTimer with a processing function called when the timer expires. This function prints an error message and exits with EXIT_FAILURE.

Please note that in the current implementation, it is not possible to reset the watchdog.
