[process] distinguish normal exit from termination by signal - complete

Boost - Users mailing list
Hello,
I'm evaluating boost.process. It seams to me that it is impossible to distinguish a normal exit from a termination by a signal (for instance SIGBUS etc.).
child::exit_code() calls eval_exit_status() that expands on POSIX to:

if (WIFEXITED(code)) {
   return  WEXITSTATUS(code);
} else if (WIFSIGNALED(code)) {
   return WTERMSIG(code);
} else {
   return code;
}

With the code above it is impossible if the returned exit_code is a `exit-code` or the number of a signal.
Or do I miss something?

regards,
Oliver
