[boost] [boost.thread] Documentation code error

16 Mar 2013

      Hello,

In the chapter about synchronization in the boost.thread documentation, 
where the hello world example with the bank account is being shown, I see a 
small problem in the class:

    int GetBalance() {
        mtx_.lock();
        int b = balance_;
        mtx_.unlock();
        return balance_;
    }

I believe it should be:

    int GetBalance() {
        mtx_.lock();
        int b = balance_;
        mtx_.unlock();
        return b;
    }

Kind regards,

Philip Bennefall
