QMutex::tryLock can lead to deadlocks when being called repeatedly. Attached is a file that will reproducible hang up sooner or later (or trigger "QMutex: mutex destroy failure: Device or . Detailed Description. The QMutex class provides access serialization between threads. The purpose of a QMutex is to protect an object, data structure or section of code so that only one thread can access it at a time (this is similar to the Java synchronized keyword). It is usually best to use a mutex with a QMutexLocker since this makes it easy to ensure that locking and unlocking are. Detailed Description.

Now, the mutex will always be unlocked when the QMutexLocker object is destroyed (when the function returns since locker is an auto variable).. The same principle applies to code that throws and catches exceptions. An exception that is not caught in the function that has locked the mutex has no way of unlocking the mutex before the exception is passed up the stack to the calling function. Hello friends. Im beginner in Qt.I watched Voidrealms tutorial (C++ Qt 31 - QThread part 4 threads with a GUI). when i want to create & run similar project, in Application output appears "QMutex: destroying locked mutex" & the thread doesnt work. even original project that wriitten by voidRealms doesnt work for me. whats the problem?.

I read @skyhisi post and more articles about QMutex and sharing variables. For education purpose i implemented a simple/clear sample of QMutex usage for sharing variable (this case counter). We would like to show you a description here but the site won’t allow us.You can use wizards also to create plain C or C++ projects that use qmake, Qbs, or CMake, but do not use the Qt library. In addition, you can import projects as. That's basically saying that 'lock' is not a member of 'QMutex'! Do any of your projects have a function or variable called "ScopedLock"?. The implementation is very similar to the Fortune Client example, but instead of having QTcpSocket data members from different threads concurrently, we use QMutex to synchronize access. . blockingfortuneclient/macrodroid.xyz . In Qt already, QMutex got revamped to be fast. In the But the problem is that , before Qt , QReadWriteLock's implementation was not as . Here is the benchmark that was run: macrodroid.xyz The Qt alternative would be QMutex. Note that it That is one major grim why certain clients drop using Qt in projects in my experience. This is. has shown is that QMutex include miss (but Qt doesn't give me this question is why the same project in QT closes itself graceful?. If accesses to the buffer were guarded by a QMutex, the consumer thread couldn't An alternative to using QSemaphore to solve the producer-consumer problem is to use QWaitCondition and QMutex. . threads/semaphores/macrodroid.xyz The consumer thread reads the data as it is produced and writes it to standard If accesses to the buffer were simply guarded by a QMutex, the consumer . threads/waitconditions/macrodroid.xyz · threads/waitconditions/waitconditions .pro.
