I’m writing a simple console based MIDI player (Linux) just to test some midi ideas. No GUI classes, so no JUCEApplication either. The single threaded one worked beautifully, using Time::waitForMillisecondCounter [didn’t expect the timing to be so rock solid, but I’m on a realtime kernel here].
Anyway so I decided to put the midi file playing logic in a separate thread, started from the int main(), and have a while loop to read keyboard commands to stop/quit.
I subclassed Thread - class MidiPlayerThread : public Thread - and implemented run(), as well as a custom function setParams (to set midi file name, midi device etc.). In the run() function’s playback loop, I check threadShouldExit(), and if yes, the loop breaks, and the run() function ends. The destructor of this class sets any references to = 0.
Trouble is, when I type “q”, the main thread calls Player.stopThread(), and the playback stops. After this, I delete the thread and some other variables on the heap, and return 0. However, at this point, the program doesn’t actually exit back to the command prompt! ps -aux says the program is .
What am I doing wrong? The source code is here (~130 lines) :
EDIT: I also tried Thread.signalThreadShouldExit(). No difference. Player.isThreadRunning() says no it’s not, and just before return 0, I added cout << Thread::getNumRunningThread(), and it says 0 threads are running just before the final exit. What the hell is wrong?!
