Is it safe to assume that sources IDs returned by g_source_attach or derived
functions are never 0?
As far as I can see in the source, it is safe until a 32-bits integer
overflow. The reason to want to know it is to be able to pack the
information 'I have set up a timeout' along with the source ID necessary
to cancel it.
I always write this type of code:
if (id > 0)
g_source_remove (...);
id = g_timeout_add (...);
But I cant say whether it is common practice, acceptable or
advisable; personally I've made the assumption that its the
way to go :-/
