Synopsis
mongoc_stream_t *
mongoc_stream_buffered_new (mongoc_stream_t *base_stream,
                            size_t           buffer_size);Parameters
| base_stream | A mongoc_stream_t to buffer. | 
| buffer_size | A size_t containing the desired buffer size. | 
This function shall create a new mongoc_stream_t that buffers bytes to and from the underlying base_stream.
buffer_size will be used as the initial buffer size. It may grow past this size.
Returns
A newly allocated mongoc_stream_buffered_t on success, otherwise NULL. This should be freed with mongoc_stream_destroy() when no longer in use.
