read through the GError doc, GError is defined as following:
struct GError {
GQuark domain;
gint code;
gchar *message;
};
I am worried about the message member, I guess program would be
aborted if OOM, which I was tring to avoid, so I used char err_msg[1024]
in my code, and make things simpler.

It is about sorting the information into following kinds:
1) static. It is values that defined at creating time/modifying time,
mostly some settings, and it would not be automatically changed in I/O.
2) dynamic. Some information that would changes in I/O and other
operations, such as allocated_size, snapshots.
3) statistics.
Now only static one is provided, so I added _static suffix.
