anymore.

.. _FileSink class: https://git.libcamera.org/libcamera/libcamera.git/tree/src/cam/file_sink.cpp
With the handling of this request completed, it is possible to re-use the
buffers by adding them to a new ``Request`` instance with their matching
streams, and finally, queue the new capture request to the camera device:
request and the associated buffers and re-queue it to the camera
device:
.. code:: cpp
request = camera->createRequest();
if (!request)
{
std::cerr << "Can't create request" << std::endl;
return;
}
for (auto it = buffers.begin(); it != buffers.end(); ++it)
{
Stream *stream = it->first;
FrameBuffer *buffer = it->second;
request->addBuffer(stream, buffer);
}
request->reuse(Request::ReuseBuffers);
camera->queueRequest(request);
