[Boost-users] thread strange

7 Jan 2008

      ...
From outside the function operator()(), I can have the pointer to
I have a strange problem with the code below.

thread object 'thread'.
...
From inside operator()() 'thread' is always 0.
Why does this happen?

------------------------------------------------------------------
#include <cstdio>
#include <boost/thread/thread.hpp>

class A
{
    boost::thread *thread;

public:
    A() : thread(0) {}
    ~A() { join(); }

    void createThread() { thread = new boost::thread(*this); }

    void operator()() {
        printf("Starting thread with pointer: %d\n", thread);           //<<<<<<<<<<<<<<HERE!
        delete thread; thread = 0;
    }

    void join() { if (thread) thread->join(); }
};

int main(int, char**) {
    A a;
    a.createThread();
    a.join();
    return 0;
}
