Detailed Description

Temporarily block all signals.

This class is used to temporarily block all signals in a critical section.

// Begin critical section
{
    senf::scheduler::BlockSignals signalBlocker;

    // critical code executed with all signals blocked
}
// End critical section

    You need to take care not to block since even the watchdog timer will be disabled while
    executing within a critical section.
