This class defines an object that provides exclusive access to the critical sections defined by this component's macros. Multiple Guard objects can exist at once, but only in the same thread ‐‐ if an attempt is made to construct a Guard while any Guard`s exist in other threads, the constructor will block until all `Guard objects in other threads are destroyed. The behavior is undefined if a Guard object is anywhere but on the stack.
