mongoc_stream_buffered_new (mongoc_stream_t *base_stream,
- A mongoc_stream_t to buffer.
- 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.
A newly allocated mongoc_stream_buffered_t on success, otherwise NULL \&. This should be freed with mongoc_stream_destroy(3) when no longer in use.
