       Reads from the GridFS file and writes to the destination stream.

       Writes  the  full  contents  of the file to the destination stream.  The destination stream is not closed
       after calling mongoc_gridfs_bucket_download_to_stream(); call mongoc_stream_close() after.

       This function is considered a retryable read operation.  Upon a transient error (a network error,  errors
       due  to  replica set failover, etc.) the operation is safely retried once.  If retryreads is false in the
       URI (see mongoc_uri_t) the retry behavior does not apply.

       • bucket: A mongoc_gridfs_bucket_t.

       • file_id: A bson_value_t of the id of the file to download.

       • destination: A mongoc_stream_t which receives data from the downloaded file.

       • error: A bson_error_t to receive any error or NULL.

       True if the operation succeeded. False otherwise, and sets error.

       SEEALSO:mongoc_stream_file_new() and mongoc_stream_file_new_for_path(), which can be used to create a destination stream from a file.
