Function sigusr1_handler

examples/Protonect.cpp:60–71

Doing non-trivial things in signal handler is bad. If you want to pause, do it in another thread. Though libusb operations are generally thread safe, I cannot guarantee everything above is thread safe when calling start()/stop() while waitForNewFrame().

//everything above is thread safe when calling start()/stop() while
//waitForNewFrame().
void sigusr1_handler(int s)
{
  if (devtopause == 0)
    return;
/// [pause]
  if (protonect_paused)
    devtopause->start();
  else
    devtopause->stop();
  protonect_paused = !protonect_paused;
/// [pause]
}

//The following demostrates how to create a custom logger
/// [logger]
