• Where is the encfs volume key stored?

  - by Waldorf

  I am trying to use encfs in reverse mode. I understand that the passphase is used to encrypt a key which is then stored encrypted into the encfs6.xml file. What I do not understand is the following. Create en encrypted virtual fs of a folder by using passphrase A unmount this folder. Delete all contents including the encfs6.xml file If you then try to do the same with another passphrse I would expect that a new encfs6.xml would be created. However I get the following error message: "Error decoding volume key, password incorrect" So I wonder, what volume key is incorrect, I thought it was in the encfs6.xml file ?

• How to implement a timer callback that executes in the same execution context

  - by Waldorf

  Some programming environments like C++ builder have timer components with a callback function which executes in the same execution contexts as where the timer object is created. I was wondering how to do something similar in plain c++ with threading. Or are there any other ways to have a callback which is periodically called to perform some task and runs in the same execution context as the calling thread?

• Windows setevent processsing

  - by Waldorf

  I wonder how setevent is handled internally within Windows. I have the following situation Std::thread thread loop which executes while std::atomic == true Inside the loop is a waitforsingleObject which sleeps infinite in alertable state. A function stopThread() which does the following: - Clears the atomic bool - Calls Setevent on the event object - Calls thread.join This often hangs, I get the impression that setevent has still some work to do in the current thread, while join blocks the current thread. If I add an additional Boolean in the thread which is set after waitforsinlgleObject and I wait for this to be set before calling join() Everything seems to work ok. Code (error checking omitted here) Init code/declarations: HANDLE m_WakeupThreadEvent; std::atomic<bool> m_ReceiverEnabled; m_WakeupThreadEvent = CreateEvent(NULL, false, false, "RxThreadWakeupEvent" ); Thread code: while(m_ReceiverEnabled) { DWORD rslt = WaitForSingleObjectEx(m_WakeupThreadEvent, INFINITE, true); // Here some checking for rslt; } function code: m_ReceiverEnabled = true; SetEvent( m_WakeupThreadEvent ) m_Thread.join() Is there some explanation for this behavior ? I could not find any details about the operation of setEvent()
