Does gen_server:cast(...) guarantee that message is received in the same order as they are sent?
I do like to call gen_server:call(...) but it contains callback to calling Module (gen_fsm) and that apparently creates race condition!
My requirement is to process message in exactly the same order as it is received.
Thanks :) |

for sure if one process sends out two messages to another process they will arrive in the same order.
In case of asynchronous calls from many processes to target one it is not guaranteed at all.
