* By default, #GBufferedOutputStream's buffer size is set at 4 kilobytes.
*
* To create a buffered output stream, use g_buffered_output_stream_new(), or
* g_buffered_output_stream_new_sized() to specify the buffer's size at construction.

* or g_buffered_output_stream_new_sized() to specify the buffer's size
* at construction.
*
* To get the size of a buffer within a buffered input stream, use
* g_buffered_output_stream_get_buffer_size(). To change the size of a
* buffered output stream's buffer, use g_buffered_output_stream_set_buffer_size().
* Note: the buffer's size cannot be reduced below the size of the data within the
* buffer.
