#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: attempting 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.
