wxMutexLocker

This is a small helper class to be used with wxMutex objects. A wxMutexLocker acquires a mutex lock in the constructor and releases (or unlocks) the mutex in the destructor making it much more difficult to forget to release a mutex (which, in general, will promptly lead to serious problems). See wxMutex for an example of wxMutexLocker usage.

bool IsOk() const
