control ESC key myself.I think if you write an osgGA::GUIEventHandler that reports that youhandled the ESC key (by returning true), the viewer won't do its ownprocessing.--Alberto Jean-Sébastien Guay 2012-08-04 21:51:50 pthread_cond_t example in c UTC PermalinkRaw Message Post by Alberto LuacesI think if you write an osgGA::GUIEventHandler that reports that youhandled the ESC key (by returning true), the viewer won't do its ownprocessing.In addition to this, I suggest you look into the following methods ofthe osgViewer::ViewerBase class (which both CompositeViewer and Viewerinherit):/** Set the key event that the viewer checks on each frame tosee if pthread cond init the viewer's done flag should be set to* signal end of viewers main loop.* Default value is Escape (osgGA::GUIEVentAdapter::KEY_Escape).* Setting to 0 switches off the feature.*/void setKeyEventSetsDone(int key) { _keyEventSetsDone = key; }/** get the key event that the viewer checks on each frame tosee if the viewer's done flag.*/int getKeyEventSetsDone() const { return _keyEventSetsDone; }/** if the flag is true, the viewer set its done flag when aQUIT_APPLICATION is received, false disables this feature */void setQuitEventSetsDone(bool flag) { _quitEventSetsDone = flag; }/** @return true if the viewer respond to theQUIT_APPLICATION-event */bool getQuitEventSetsDone() const { return _quitEventSetsDone; }Hope this helps,J-S--______________________________________________________Jean-Sebastien Guay jean_seb-XzQKRVe1yT0V+D8aMU/***@public.gmane.orghttp://whitestar02.dyndns-web.com/ michael kapelko 2012-08-05 05:39:24 UTC PermalinkRaw Message Thanks. ViewerBase::setKeyEventSetsDone(0) did help so that Viewerdoesn't listen to ESC, but now when I call ViewerBase::setDone(true)myself, Viewer still fails to exit and prints:Error: pthread_cond_destroy(,) returned error status, status = 16after that, only Ctrl+C helps, because app hangs.What is this and how do I fight it?Thanks. 3 Replies 3 Views Switch to linear view Disable enhanced parsing Permalink to this page Thread Navigation michael kapelko 2012-08-04 08:03:00 UTC Alberto Luaces 2012-08-04 18:

Pthread Cond Example
trying to use gProof->GetManager()->GetFile in the (compiled) program after a PROOF session and in such a case GetFile hangs at 16Kb or so. It doesn't work even when http://osg-users.openscenegraph.narkive.com/79t3fVfQ/esc-key-error-pthread-cond-destroy-returned-error-status-status-16 I'm closing the session first and then call TProof::Mgr(

root [0] TProof::Mgr("lxslc22")->GetFile("/afs/ihep.ac.cn/users/e/eugenyboger/root/bin/xrd","/tmp/")

9 years ago Fix "Error freeing dispatch queue" Reported by: dsmith Owned by: dsmith Priority: minor Milestone: Version 1.0 Component: libcwiid Version: 0.5.02 Keywords: pthread dispatch queue Cc: Description I get an occasional error message (listed above). Due to race condition/multi-threading issue, probably in dispatch cancellation logic. Change History Changed 10 years ago by dsmith status changed from new to assigned Changed 10 years ago by dsmith status changed from assigned to closed resolution set to wontfix Changed 10 years ago by etaurel@… status changed from closed to reopened resolution wontfix deleted Hi, I think there is a way to solve this problem. The error comes from the "queue_free" function of the queue management and more specifically from the "pthread_cond_destroy()" in this function. This call returns the error code EBUSY. I think this system call returns this error due to the thread cancellation while it was waiting in the same condition variable (only a guess) Anyway, by modifying the code in the following way, I do not have error message any more. while (pthread_cond_destroy(&queue->cond) == EBUSY) { pthread_cond_broadcast(queue->cond); } The code passes only once in this loop. Hoping this help Emmanuel Taurel Changed 10 years ago by dsmith I'll leave the ticket open in case there's another 0.5 release, but the API overhaul in 0.6 gets rid of the queues. I hadn't noticed that one, but there's another condition in which the dispatch thread can try to lock a mutex that's already been destroyed. Thanks for the fix. Changed 9 years ago by dsmith status changed from reopened to closed resolution set to wontfix To be reopened if there's another 0.5 release (unlikely).
