Xiangfei,

Docs indicate doing something like this:

void
FrameNode::read_new_data()
{
    bool done = false ;
    while( !done )
    {
       [do something]
    }

    throw Glib::Thread::Exit() ;
}

Thanks for  your reply!! I tried to put "throw Glib::Thread::Exit()" at the end of my thread function. It's not working. I've still got the error message when the program is exiting.
 

What you've probably got at issue is guranteeing that all of your
threads have exited before you attempt to close your program.  My guess
is that you've got a thread waiting on a condtion variable when an
attempt to destroy the condition variable is made.

Yes, you are right. The thread is  always  running and reading new data from a file and  waiting for the new data to be consumed and then read more new data.

I can't make the thread joinable, because the thread is always running during program execution. What I want to do is to exit the thread just before the program is going to exit. That's what I don't know how to achieve.

Thanks again!
