async_write_at

The async_write_at function is a composed asynchronous operation that writes a certain amount of data at the specified offset before completion.

Start an asynchronous operation to write all of the supplied data at the specified offset.

template<
    typename AsyncRandomAccessWriteDevice,
    typename ConstBufferSequence,
    typename WriteHandler = DEFAULT>
DEDUCED async_write_at(
    AsyncRandomAccessWriteDevice & d,
    uint64_t offset,
    const ConstBufferSequence & buffers,
    WriteHandler && handler = DEFAULT);
