What is the difference between
MyClass* myClass = new MyClass;
std::thread myThread( &MyClass::MyMemberFunction, myClass );
std::thread( &MyClass::MyMemberFunction, myClass );
P.S. Trying to put boost::asio::io_service into separate thread using second approach - doesn't work. But first one does. Both approaches work if change std to boost.
WIndows 7. MSVS 12.0.
The first one creates a thread object, which you must either detach or join at some point.
The second creates and destroys a temporary thread, terminating the program because you didn't detach or join it. Boost allowed that, automatically detaching threads on destruction; but that behaviour can lead to subtle errors, so the standard library forces you to make an explicit choice.
If you really want a "fire and forget" thread, you could do
std::thread( &MyClass::MyMemberFunction, myClass ).detach();
but it's usually better to keep a thread object to join at a suitable time, especially if you're planning to
delete myClass at some point.
