// Do note that the reply here is a NEGATION of bitflags reported for

// These services are not for calling by general modules. They serve a specific
// role in communicating through protocol module chains before the whole app is
// notified that an event has occurred.
// When the respective event is received over the network, the network-level
// protocol module initiates the chain by calling MS_PROTO_CHAINRECV with wParam
// set to zero and lParam pointing to the CCSDATA structure.
// Protocol modules should continue the message up the chain by calling
// MS_PROTO_CHAINRECV with the same wParam they received and a modified (or not)
// lParam (CCSDATA). If they do not do this and return nonzero then all further
// processing for the event will cease and the event will be ignored.
// Once all non-network protocol modules have been called (in reverse order),
// the network protocol module will be called so that it can finish its
// processing using the modified information.
// This final processing should consist of the protocol module adding the
// event to the database, and it is the ME_DB_EVENT_ADDED event that people who
// just want to know the final result should hook.
// In all cases, the database should store what the user read/wrote.
