Hi,
I'm sure the question is very banal...
I have a thread object stored in a class:
class MyClass {
private: void Init(); boost::thread _thread; }
How can I create it in the implementation code?
MyClass::Init() { // start thread here... }
Hi, You can not. Thread is default constructible but not copy constructible. You can do MyClass() : _thread(fct) {} If you want to start the thread later on you need a pointer to a thread class MyClass { private: void Init(); scoped_ptr<boost::thread> _thread; } MyClass() : _thread(0) {} MyClass::Init() { _thread.reset(new boost::thread(fct)); .... } If you can not have a pointer, you can use a volatile boolean as follows: voif fct(volatile bool& started) { while(!started) ; // start here the real function } MyClass() : _started(false), _thread(bind(fct, _started)) {} MyClass::Init() { _started=true; .... } BTW, why do you want to start the thread on the Init function and not on the constructor? HTH, Vicente
