Re: Launching an app from Carbon app (newbie question)

The fork and execve works now, but unfortunately, it still has not solved my problem. What happens now is that if I make the parent process waitpid, then the parent goes to sleep, and the children keep running, with the application update happening successfully, but I can only tell because I can see the console output. The children never get the UI back, and the parent is still sitting in the task bar at the bottom, but since it is asleep, I can't interact with it. This leaves me in what is effectively a deadlocked situation. Its some progress at least :)

I tried using execve, but I always get a ENOTSUP returned from

execve() will return ENOTSUP if your process has more than one
thread. Forking will fix this, though - try something more like...

pid_t p = fork();
if(p < 0)
{
  scream_bloody_murder();
  return;
}

if(p == 0)
{
  execve(whatever);
}
exit(0);
