sync() -> true


Synchronize with the gproc leader This function can be used to ensure that data has been replicated from the leader to the current node. It does so by asking the leader to ping all live participating nodes. The call will return `true` when all these nodes have either responded or died. In the special case where the leader dies during an ongoing sync, the call will fail with a timeout exception. (Actually, it should be a `leader_died` exception; more study needed to find out why gen_leader times out in this situation, rather than reporting that the leader died.) ###terminate/2## `terminate(Reason, S) -> any()` ###unreg/1## `unreg(Key) -> any()` ###unreg_shared/1## `unreg_shared(Key) -> any()` ###update_counter/2## `update_counter(Key, Incr) -> any()` ###update_counters/1## `update_counters(List) -> any()` ###update_shared_counter/2## `update_shared_counter(Key, Incr) -> any()`
