@dom96, you are the author of async libraries, don't you? Maybe you can help me with it. Here is my experiments with it: [https://github.com/vegansk/Nim/tree/async_buffers](https://github.com/vegansk/Nim/tree/async_buffers). I don't want to create the PR right now. Here is the problem. The tests works on windows, when I implement `send` via `sendBuffer`: [https://github.com/vegansk/Nim/blob/async_buffers/lib/pure/asyncdispatch.nim#L865](https://github.com/vegansk/Nim/blob/async_buffers/lib/pure/asyncdispatch.nim#L865). But it fails on Linux in tests/async/tasyncawait.nim if I implement `send` like this: proc send*(socket: AsyncFD, data: string, flags = {SocketFlag.SafeDisconn}): Future[void] = ## Sends ``data`` to ``socket``. The returned future will complete once all ## data has been sent. var c = data socket.sendBuffer(addr c[0], data.len, flags)
and when I copy `sendBuffer`'s body, to `send` ([https://github.com/vegansk/Nim/blob/async_buffers/lib/pure/asyncdispatch.nim#L1464](https://github.com/vegansk/Nim/blob/async_buffers/lib/pure/asyncdispatch.nim#L1464)) it's just works.
