Hi !

I've created two simples classes that helped me avoid data races when sharing objects among threads.

The idea is to declare objects that need for synchronization as Synchronized<T>, which holds a T and a mutex. To use the T, a Get function has to be called that returns a proxy, which holds a pointer to the T and a scoped lock on the mutex. The proxy defines operator-> and operator* to give access to the T. To have acces to the T, one has to create the proxy. As long as the proxy exists, the mutex associated with the T is locked, effectively preventing use by other threads.

I have one that does reader/writer locking. I'll pass it along for comparison along with design notes (it was done partially for teaching), if it's OK to send a zip file to you. —John
