/**
 * Buffered output stream implements #GFilterOutputStream and provides
 * for buffered writes.
 * 
 * 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.
 * 
 * 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 that the buffer's
 * size cannot be reduced below the size of the data within the buffer.
