I presume that I have to use GLib.Subprocess instead of GLib.Process... Ok.
Thanks!

the spawned program is always stored in the upper 8 bits?
I can give some insight based on my own experience, which boils down to: - use
GLib SubProcess - use the Open Group documentation for anything that is unclear
with POSIX (Unix)
https://valadoc.org/gio-2.0/GLib.Subprocess.get_exit_status.html states 'This
is equivalent to the system WEXITSTATUS macro' and
http://pubs.opengroup.org/onlinepubs/9699919799/functions/wait.htmlstates
'WEXITSTATUS(stat_val) If the value of WIFEXITED(stat_val) is non-zero, this
macro evaluates to the low-order 8 bits of the status argumentthat the
childprocess passed to _exit() or exit(), or the value the child process
returned from main()'
I hope that helps.
