Detailed Description🔗

class iox::posix::SignalWatcher;

The SignalWatcher waits for SIGINT and SIGTERM. One can wait until the signal has occurred or ask the watcher if it has occurred.

// can be used to loop until SIGINT or SIGTERM has occurred
#include <iceoryx_hoofs/posix/signal_watcher.hpp>
void loopUntilTerminationRequested()
{
    while(!iox::posix::hasTerminationRequested())
    {
        // your algorithm
    }
}

// another possibility is to block until SIGINT or SIGTERM has occurred
void blockUntilCtrlC() {
    // your objects which spawn threads
    iox::posix::waitForTerminationRequest();
}
