There was a similar question about this topic some time ago. For a
response see:

You'll probably need to check the backend homepages.

IIRC and completely untested:

fork ...
  exec ...
  
  waitpid (pid, &status)
  
Examine the status with  WIFEXITED(status) and WEXITSTATUS(status).
See manpages for details.

Bye,
