If your application (somehow) doesn't have to communicate with anything else and wait for it to respond, use `async def`, even if you don't need to use `await` inside.

---

If you just don't know, use normal `def`.

**Note**: You can mix `def` and `async def` in your *path operation functions* as much as you need and define each one using the best option for you. FastAPI will do the right thing with them.

### Setup your MinIO GitHub Repository

Fork [MinIO upstream](https://github.com/minio/minio/fork) source repository to your own personal repository. Copy the URL of your MinIO fork (you will need it for the `git clone` command below).

```sh
git clone https://github.com/minio/minio
cd minio
go install -v
ls $(go env GOPATH)/bin/minio
```

### Set up git remote as ``upstream``

```sh

        void returnsFour_whenStructureSizeIsFour(int start) throws Exception {
            // Arrange: build a buffer that has the little-endian value 4 at 'start'
            int len = start + 2; // need at least two bytes from start
            byte[] buffer = new byte[len + 3];
            SMBUtil.writeInt2(4, buffer, start);
            Smb2LogoffResponse resp = newResponse();

            // Act
