Construct a basic_random_access_file
on
an existing native file.
template< typename ExecutionContext> basic_random_access_file( ExecutionContext & context, const native_handle_type & native_file, typename constraint< is_convertible< ExecutionContext &, execution_context & >::value, defaulted_constraint >::type = defaulted_constraint());
This constructor initialises a random-access file object to hold an existing native file.
An execution context which provides the I/O executor that the file will use, by default, to dispatch handlers for any asynchronous operations performed on the file.
The new underlying file implementation.
