Absolutely. But a slightly more high level overview really helps in this task.

Ok, I understand now, thank you very much! I just have one more
question about this. How are variable-sized rows handled? Are they
still recorded in this buffer (the record buffer passed to write_row),
or do I have to go through the fields manually, one by one? If
variable length rows are recorded into this buffer, how can I
determine its length without looking at every field?
From what I understand if the table contains no blobs and has fixed
size records, I can dump the buffer passed to write_row into the file
as is (this is what I'm doing now). If it has blobs, I have to go
through the fields to handle blobs properly. Now, variable-sized rows
and I'm completely unclear about.
