Description
-----------

Reads from the ``source`` stream and writes to a new file in GridFS. The file id is generated automatically.
To specify an explicit file id, use :symbol:`mongoc_gridfs_bucket_upload_from_stream_with_id()`.

Reads from the ``source`` stream using :symbol:`mongoc_stream_read()` until the return value indicates end-of-file.
The ``source`` stream is not closed after calling :symbol:`mongoc_gridfs_bucket_upload_from_stream()`; call :symbol:`mongoc_stream_close()` after.

See Also
--------
:symbol:`mongoc_stream_file_new` and :symbol:`mongoc_stream_file_new_for_path`, which can be used to create a source stream from a file.

Returns
-------
True if the operation succeeded. False otherwise and sets ``error``.
