My APIs seems to be written to work only from a user space program.
The file this API is tring to access is /dev/cif and looking at to the source, I
can found some copy_from_user functions and other user-kernel oriented
communication functions.
All operations over this special file are made by user functions like:open, close,
seek, ecc... but I can't override the copy_from_user and copy_to_user functions
without make big changes to the driver.
I'm not so expert in device driver programming and I don't know how much time this
will need.
Do you think the only way is to rewrite all APIs ?
Bye, Thomas.
