示例1: read
bool read(PortReader& reader, bool willReply = false) {
// called by user
// user claimed they would reply to last read, but then
// decided not to.
if (replyDue) {
Bottle emptyMessage;
reply(emptyMessage,false,false);
replyDue = false;
dropDue = false;
}
if (willReply) {
replyDue = true;
}
stateMutex.wait();
readActive = true;
readDelegate = &reader;
writeDelegate = NULL;
this->willReply = willReply;
consume.post(); // happy consumer
stateMutex.post();
produce.wait();
stateMutex.wait();
if (!readBackground) {
readDelegate = NULL;
}
stateMutex.post();
bool result = readResult;
return result;
}示例2: clear
virtual ~Private()
{
Port *closePort = nullptr;
stateSema.wait();
if (port!=nullptr) {
closePort = port;
}
stateSema.post();
if (closePort!=nullptr) {
closePort->close();
}
stateSema.wait();
clear();
//stateSema.post(); // never give back mutex
}示例3: configReader
