I have written a class with static methods and properties. Now the class must be used in a multithreaded environment, so I get some race conditions error. I use boost::thread for implementating the threads. I have found boost_once but I don't know how to use it, so my class properties are initialized once.

I know Google and so I've found boost_once, but can you show me a little example?

He was hinting at something, look at the very first result on that Google link.

The first example http://www.boostcookbook.com/Recipe:/1235044 don't have static members, because myclass is a class with is a master class of the Singleton. In my class I've got a static property of the boost mersenne twister and get the rase condition error on it's get method: boost::detail::backward_compatible_uniform_01&>, double>::operator()()
