How to tell whether Stat constructor worked?
This looks like it could be a bug in the binding, but maybe there's just something missing in the docs:
g_stat returns an int indicating success or failure, but I can't see any way in
glib-2.0.vapi that the success or failure is signalled: the return code seems to be discarded.
If there is a way to determine success or failure, please could it be documented?
