Or just don't use boost:ref, and have the thread function objects copied.
Rene, is that possible with a stuct?
Yes, as long as it has default and copy ctors (or usually the auto generated ones).
the problem is that i need give the thread some initial parameters, and i'm not sure if thats possible using a simple function.
The most elegant solution is to use Boost.Bind. For example your original code could be written as such: #include <iostream> #include <boost/thread.hpp> #include <boost/shared_ptr.hpp> #include <boost/bind.hpp> void simple_thread(int i) { std::cout << i << std::endl; } int main() { boost::thread_group threads; for ( int i = 0 ; i < 5 ; ++i ) { threads.create_thread( boost::bind(&simple_thread,i) ); }; threads.join_all( ); return 0; }
if a thread is created using new simple_thread* trd = new simple_thread( p ); and started using: threads.create_thread( boost::ref( *trd ) ); trd still needs to be destroyed using "delete" somewhere right?
Yes.
or will the memory be free'd when the thread finishes execution?
