Construct an overlapped handle on an existing native handle.
template< typename ExecutionContext> basic_overlapped_handle( ExecutionContext & context, const native_handle_type & native_handle, typename constraint< is_convertible< ExecutionContext &, execution_context & >::value >::type = 0);
This constructor creates an overlapped handle object to hold an existing native handle.
An execution context which provides the I/O executor that the overlapped handle will use, by default, to dispatch handlers for any asynchronous operations performed on the overlapped handle.
The new underlying handle implementation.
Thrown on failure.
