basic_random_access_file::basic_random_access_file (8 of 10 overloads)

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.

Parameters

context: 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.
native_file: The new underlying file implementation.

Exceptions

asio::system_error: Thrown on failure.
