| * @short_description: Buffered Output Stream |
| * @include: gio/gio.h |
| * @see_also: #GFilterOutputStream, #GOutputStream |
| * |
| * 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. |
