Description 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.
