I'm looking at the source code for drip in 2.1.0 and dissemination in 2.0
(which is the same for DisseminationEngineImplP.nc).
There's an event:
event message_t* ProbeReceive.receive( message_t* msg,
void* payload,
uint8_t len) {
dissemination_probe_message_t* dpMsg =
(dissemination_probe_message_t*) payload;
if ( !m_running ) { return msg; }
if ( call DisseminationCache.requestSeqno[ dpMsg->key ]() !=
DISSEMINATION_SEQNO_UNKNOWN ) {
sendObject( dpMsg->key );
}
return msg;
}
and command:
default command uint32_t
DisseminationCache.requestSeqno[uint16_t key]() { return
DISSEMINATION_SEQNO_UNKNOWN; }
My question is "when will the condition ( call DisseminationCache.requestSeqno[
dpMsg->key ]() !=
DISSEMINATION_SEQNO_UNKNOWN ) be true?"
In other words, call DisseminationCache.requestSeqno[ dpMsg->key ]() will
ALWAYS equal DISSEMINATION_SEQNO_UNKNOWN, won't it?
Is that code compiled out, or, better, yet, what was that code supposed to do?
Regards,
Kurt
