<p>A basic managed windows shared memory creation class. Initializes the shared memory segment. Inherits all basic functionality from basic_managed_memory_impl<CharType, AllocationAlgorithm, IndexType> Unlike basic_managed_shared_memory, it has no kernel persistence and the shared memory is destroyed when all processes destroy all their windows_shared_memory objects and mapped regions for the same shared memory or the processes end/crash.</p>
<p>Warning: basic_managed_windows_shared_memory and basic_managed_shared_memory can't communicate between them. </p>
