Here you go. Sorry for having missed it in my previous reply.


[DllImport ("libc")]
        private static extern int execv (string cmd, string[] args);

execv ("/tmp/myscript", (string[]) list.ToArray (typeof (string)));
list is Array list with set of arguments. Not NULL terminated.


I have further error messages on this application which failed with mono 1.2.0 version too.
Please fine it below.
