elapses. If we get bytes but there's nobody asking for them, we buffer them. We don't consider bytes as delivered for flow control until they're consumed by the application.

Consider an application streaming a video over http/2. Perhaps the user pauses the video and the application stops reading bytes from this stream. The buffer will fill up, and flow control prevents the server from sending more data on this stream. When the user unpauses her video the buffer drains, the read is acknowledged,...

### This jcifs or jcifs-ng

  // is more specialized.  (The C++ Standard, section
  // [temp.func.order].)  If you stream a non-pointer, then the
  // previous definition will be used.
  //
  // The reason for this overload is that streaming a NULL pointer to
  // ostream is undefined behavior.  Depending on the compiler, you
  // may get "0", "(nil)", "(null)", or an access violation.  To
  // ensure consistent result across compilers, we always treat NULL

# Custom Response Classes - File, HTML, Redirect, Streaming, etc.

There are several custom response classes you can use to create an instance and return them directly from your *path operations*.

Read more about it in the [FastAPI docs for Custom Response - HTML, Stream, File, others](https://fastapi.tiangolo.com/advanced/custom-response/).

You can import them directly from `fastapi.responses`:

```python
from fastapi.responses import (
