Re: Why g_spawn_async return a null pid under Windows?

["Dominic Lachowicz" <domlachowicz gmail com>]

I think that you need to pass the G_SPAWN_DO_NOT_REAP_CHILD flag. On
Win32, g_spawn_async() won't return the PID otherwise. If you don't
pass that flag, the pid you get back would be pretty meaningless, as
glib may have already reaped it.

Also, this list of more for the development of GTK+ and Glib
themselves. In the future, you should post questions like this to the
gtk-app-devel list.

Cheers,
Dom
