Linux best practice to run and view another process

Question

In my process, I need to start / restart another process. I am currently using a stream with a small stack size and the following code:

void startAndMonitorA()
{
  while(true)
  {
    system("myProcess");
    LOG("myProcess crashed");
    usleep(1000 * 1000);
  }
}

I feel that this is not the best practice. I have no idea about the resources that the call is std::system()blocking or wasting. I am in embedded Linux - so in general I try to take care of resources.
