I was just looking at gatomic.c to see if g_atomic_int_compare_and_exchange() would work on an integer inside memory obtained by mmap(MAP_SHARED) safely between processes. With my limited understanding it looks like it probably would except for the cases when it has to fall back to g_mutex_()* ops on g_atomic_mutex. I started to look at gthread.c to see if the mutex implementations themselves might be based on inter-process capable mutex technologies, but I'm not following along so well in there.
So my questions are: -were any of the atomic functions intended for process shared memory or just thread shared memory? -even if that is not the case, would the non-mutex based implementations work in that fashion? -is there a way to test for what implementation is being used?
