Default behaviour. Since: 2.74
If this flag is given, the child process will inherit the parent's stderr. Otherwise, the child's stderr will not be visible, but it will be captured to allow later tests with GLib.test_trap_assert_stderr.
If this flag is given, the child
process will inherit the parent's stdin. Otherwise, the child's
stdin is redirected to /dev/null.
If this flag is given, the child process will inherit the parent's stdout. Otherwise, the child's stdout will not be visible, but it will be captured to allow later tests with GLib.test_trap_assert_stdout.
Flags to pass to GLib.test_trap_subprocess to control input and output.
Note that in contrast with GLib.test_trap_fork, the default behavior of GLib.test_trap_subprocess is to not show stdout and stderr.
