Re: [Boost-users] boost::thread passing reference of the data object tothread func does not work

Xiaofan Li: ...

for (int i = 0; i < 10; ++i) threads.create_thread( boost::bind( boost::mem_fn( &threaded::increment_count ), &_thrd, a ) );

Use boost::bind( &threaded::increment_count, &_thrd, boost::ref( a ) ) to make boost::bind store a reference to 'a', rather than a copy.
