The same code as a standalone program is really not the same code. I would really recommend against using CRTL methods for creating subprocesses from XS code. When you are writing XS you are extending Perl, so you should do whatever Perl does. In this case, that probably means calling Perl_pp_system or Perl_do_spawn. ________________________________________ Craig A.
