Hi,
My problem - I have to intercept open&write function calls to .vdi file
when VirtualBox is working to control which sectors of vdi file were
changed, i.e. I need to get 1. what file was open for writing; 2. data
from buffer; 3. size of data; 4. offset in file;
I tryed:
- LD_PRELOAD - not helped
- using fuse - rewrote write call and successfully
intercepted, but fuse is slow.
I have possibilities to patch ext3 or patch inotify.
Is there any better way to do it?
TIA
