[omniORB] Re: omniORB and fork()

[Sai-Lai Lo]

I assume you are talking about linux, fork() and execv() works fine as far
as I can tell.

Example, this works with eg3_impl:

char* Echo_i::echoString(const char* mesg)
{
  if (fork() == 0) {
    char* argv[] = { "date", 0 };
    execv("/bin/date",argv);
  }
  else {
    int status;
    wait(&status);
  }

  return CORBA::string_dup(mesg);
}
