[fuse-devel] Can i modify write offset?

[Tuan N. <tua...@gm...>]

Hi everyone,
I'm learning about fuse development.And i have stuck with write callback.
i'm writing encryption on the fly using fuse.My protected file
includes 256bytes header to detect my file.
in write callback,i'm modified the write offset to write header.It
works with text,.pdf file
but failed with .doc file<using microsoft office 2011>.Word notified
cannot save to .tmp file.
what's i wrong and can anyone help me to resolve it?
Thanks so much.

regards,
AT.
