/**
* #GSeekable is implemented by streams (implementations of
* #GInputStream or #GOutputStream) that support seeking.
*
* Seekable streams largely fall into two categories: resizable and
* fixed-size.
*
* #GSeekable on fixed-sized streams is approximately the same as POSIX
* lseek() on a block device (for example: attmepting to seek past the
* end of the device is an error). Fixed streams typically cannot be
* truncated.
*
* #GSeekable on resizable streams is approximately the same as POSIX
* lseek() on a normal file. Seeking past the end and writing data will
* usually cause the stream to resize by introducing zero bytes.
