| <p><a class="link" href="GSeekable.html" title="GSeekable"><span class="type">GSeekable</span></a> on fixed-sized streams is approximately the same as POSIX |
| <code class="function">lseek()</code> on a block device (for example: attmepting to seek past the |

| truncated.</p> |
| <p><a class="link" href="GSeekable.html" title="GSeekable"><span class="type">GSeekable</span></a> on resizable streams is approximately the same as POSIX |
| <code class="function">lseek()</code> on a normal file. Seeking past the end and writing data will |
| usually cause the stream to resize by introducing zero bytes.</p> |
